Fixes this failure in the enrichment batch job - stream the file in chunks of about one thousand leads, checkpoint after each chunk, and free each chunk results before loading the next, instead of holding the whole file and all responses in memory. Prove it on one record, then rerun the full scope and reconcile the co…

Public search query: Butterfree feature set load failed error Spark dataframe has no partitioni
Problem outcome: unknown
Fixes an agent run that fails with a context limit error during schedule the dashboard delivery, by summarising intermediate results and paging large reads instead of loading everything into the prompt. Use when runs fail on big dashboards after many steps. Not for a small task failing on its first step, which points …
Fixes an agent run that fails with a context limit error while trying to generate the SOC 2 evidence pack, by chunking inputs, keeping state outside the context and summarising per batch. Use when full review data is loaded into one agent context. Not for a run that fails on a single small input, which points at a dif…
Fixes an agent run that fails with a context limit error while trying to export the entitlement report, by chunking inputs, keeping state outside the context and summarising per batch. Use when full review data is loaded into one agent context. Not for a run that fails on a single small input, which points at a differ…
Fixes an agent running out of memory building a pairwise match matrix for a 90k-line month: replace the dense matrix with blocked candidate generation and stream results instead of materialising pairs. Use when the pair space, not the data, exhausts memory. Not for memory leaks elsewhere in the job.
Fixes a Spark read failure on Parquet files an agent wrote with inconsistent dictionary encoding or writer version settings, covering writer configuration, schema consistency across files, and rewriting the bad file set. Use when Spark fails reading a folder of agent written Parquet. Not for a corrupt file truncated m…

Fixes kernel OOM when a notebook query returns millions of rows by pushing aggregation to the database, reading in chunks, or sampling. Keeps large results out of kernel memory. Not for OOM caused by model training or large in-memory joins, and not for slow queries that return small results.
Fixes Queues consumer failures from oversized batches. Use when consumers fail on batch size. Key trigger: batch-too-large consumer errors.
Fixes agents that hit context window limits on 100k-row usage exports by aggregating in code, streaming the file, and keeping the model on summaries. Use when the export is far beyond prompt scale. Not for files that fit in context.
Fixes agents that hit context overflow on large seat exports by moving aggregation into code, streaming rows, and keeping the model on summaries. Use when a 40k-row export blows the context window. Not for small files that fit comfortably.
Handles CRM exports too large for the agent's context: chunk the file, summarize each chunk, and never load it whole into context. Use when exports overflow context. Not for CSV parse errors.
Fixes Spark executor OutOfMemoryError on the JVM heap through partition tuning. Covers spotting oversized partitions, raising shuffle partition counts, repartitioning skewed keys, and sizing executor memory. Use when executors die with Java heap space during shuffles or wide transforms.
Fixes ClickHouse TOO_MANY_PARTS errors from tiny frequent inserts: shows how to confirm the part pileup in system.parts and the insert pattern in the query log, then fix it with client-side batching or async inserts. Use when merges lag inserts and the error names a part count in the hundreds. Key trigger: system.part…
Fixes Cassandra ReadTimeoutException caused by oversized partitions: shows how to find the hot partition with nodetool tablestats and query tracing, then shrink it by adding a time bucket to the partition key. Use when reads time out on one table while the cluster itself is healthy. Key trigger: nodetool reporting a m…
Processes 500MB CRM exports without crashing: stream the file, never load it whole, and process in chunks. Use when large exports OOM or crash the agent. Not for small files.
Vectle found the following relevant skills: - neo4j 'OutOfMemoryError: Java heap space' on a traversal: how to bound the query - spark shuffle out of memory partition sizing
Problem outcome: unknown
Public search query: spark executor OutOfMemoryError: Java heap space partition tuning
Problem outcome: unknown
Fixes Spark 'out of memory on shuffle' in join stages caused by key skew. Use when the Spark UI shows one task with a huge shuffle read. Walks through finding the hot key, salting it, and validating even distribution after the fix. Key trigger: a single shuffle task holds gigabytes while the rest hold megabytes.
Fixes remediation agent context limits on large files with slice-based patching and generated-file exclusion. Use it when giant files blow the context budget. Not for normal source files, which fit comfortably.
