agent crashed with error processing a 500mb crm export

Not specified by the original author.

TL;DR

A 500MB export does not fit comfortably in memory alongside processing overhead. Stream it (read and process line by line or in chunks), write results incrementally, and checkpoint. The file is fine; loading it whole is the bug.

Error

MemoryError: unable to allocate 512 MB during export processing

Steps

1. Switch from read-all to streaming: iterate the file line by line or in fixed-size chunks. Expected: memory stays flat.
2. Process each chunk and write results incrementally (append to output, commit to database). Expected: progress is durable.
3. Checkpoint the byte offset or row count periodically. Expected: crashes resume.
4. Validate the file's encoding and delimiter on a sample before the full pass. Expected: no mid-run parse surprises.
5. If the export itself is the bottleneck, request it in smaller date ranges. Expected: manageable file sizes.

When to use

• Large exports crash the processor.
• An agent loads whole files into memory.
• Out-of-memory errors on export jobs.

When not to use

• Small files (simplicity wins).
• Export generation failures (different problem).

Tool compatibility

• Streaming file IO in any language; chunked processing.
• Export APIs with date-range filters.

Variant phrasings

out of memory on large export

Stream instead of loading.

crash processing 500mb file

Chunk and checkpoint.

Why it happens

In-memory processing multiplies the file size (parsed objects, intermediate structures). A 500MB file easily becomes gigabytes in memory, exceeding the agent's limit.

Edge cases

• Compressed exports: stream-decompress, do not decompress to disk first unless needed.
• Row counts, not just bytes, matter; wide rows blow up faster.
• Checksums verify the download before the long processing run.

Thread query: agent crashed with error processing a 500mb crm export

TL;DR: A 500MB export does not fit comfortably in memory alongside processing overhead. Stream it (read and process line by line or in chunks), write results incrementally, and checkpoint. The file is fine; loading it whole is the bug.

TL;DR

The export is bigger than the agent's context window, so loading it whole overflows. Process the file in chunks outside the context (streaming reads), keep only summaries and aggregates in context, and write details to files the agent can reference. The context window is for reasoning, not storage.

Error

Context overflow: input exceeded the model's context limit while reading the export file.

Steps

1. Stop loading the file into context. Read it with streaming code instead. Expected: the file never enters the context whole.
2. Process chunk by chunk: for dedupe, emit candidate pairs per chunk to a file. Expected: bounded context per chunk.
3. Keep running aggregates in context (counts, top issues), not raw rows. Expected: the agent reasons over summaries.
4. Write chunk outputs to files and have the agent read them selectively. Expected: details available on demand.
5. For very large files, do the heavy work in code (scripts, SQL) and use the agent for decisions on the results. Expected: the right tool for each job.

When to use

• Exports overflow the agent's context.
• An agent tries to read a whole CSV into context.
• "File too large" from the model, not the parser.

When not to use

• CSV parse errors (different fix).
• Small files (load directly, simpler).

Tool compatibility

• Streaming file processing in code.
• Agent context management.

Variant phrasings

context overflow on export

Chunk and summarize.

file too large for context

Process in code, decide in context.

Why it happens

Agents default to reading files whole. Context windows are finite and expensive; multi-megabyte exports exceed them fast.

Edge cases

• Chunk boundaries can split multi-line records; use a real CSV reader, not line counts.
• Summaries must preserve enough detail for decisions; aggregate deliberately.
• The 500MB case needs code, not clever chunking; know when to switch tools.

TL;DR

Fix this in Territory planning agent by acting on the exact message first: plan one territory segment at a time, load account identifiers with a compact firmographic summary instead of full records, and write each segment plan before loading the next segment. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one record, then rerun the full scope and reconcile the counts.

Context overflow loading the full account list plus firmographics for a territory planning pass

Use this when

• The operation in Territory planning agent fails with this exact message: Context overflow loading the full account list plus firmographics for a territory planning pass.
• The same failure repeats on retry with unchanged inputs.
• A run, import, export or alert is blocked until this item completes.

Not for this skill when

• The message is a permission or platform outage notice. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in Territory planning agent, and copy the full message plus the record, account or list involved into the run notes. Verify: the error is reproduced on demand with a named record, not only seen in a log.
2. Apply the specific fix for this error: plan one territory segment at a time, load account identifiers with a compact firmographic summary instead of full records, and write each segment plan before loading the next segment. Verify: one named record now completes end to end with the correct result and the original message does not appear.
3. Check the neighbouring records that share the same source, mapping, workspace or settings, because this class of failure rarely affects only one record. Verify: the neighbouring records are listed and each is marked affected or clear.
4. Compare the result counts, fields or alerts against the source in Territory planning agent so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in Territory planning agent on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the record so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

The pass needs segment level totals, and loading every full firmographic record for every account overflowed the context before any planning happened.

The verbatim form searchers paste from the terminal or console. Treat it identically: same fix, same single record proof, then the full rerun.

How to fix this failure in Territory planning agent

The how to phrasing for the same failure. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

Troubleshooting this failure in Territory planning agent

The symptom first phrasing used when the console hides the full message. Surface the full message first, confirm it matches the code block above, then follow the steps.

Compatibility: Territory planning agent at current versions, plus the platform API or console the query names; no extra tooling beyond the source system access needed to verify counts.
