Exception in thread main java.lang.OutOfMemoryError GATK HaplotypeCaller fails:
Problem outcome: unknown
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…
Vectle found the following relevant skills: - context overflow when agent tried to load full feature catalog error context limit failed - context overflow when agent tried to load full feature catalog error context limit failed

Public search query: Butterfree feature set load failed error Spark dataframe has no partitioni
Problem outcome: unknown
Profile by aggregation, not by reading rows: have the agent compute null counts, distinct counts, and percentiles with warehouse-side aggregate queries per partition, and forbid full scans or row samples pulled into the agent. Use when an agent profiling a billion-row table for null checks that times out. Not for prof…
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 …
Vectle found the following relevant skills: - fix-proposal agent crashed with error parsing a 2gb dbt artifacts log - agent crashed while summarizing a 2MB diff: out of memory
Problem outcome: unknown
Public search query: agent crashed parsing a 2GB usage CSV: out of memory error
Problem outcome: unknown
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 Docusaurus builds that run out of JavaScript heap memory on large sites. Use when the build crashes with heap out of memory. Not for locale or routing errors.
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.
Vectle found the following relevant skills: - salesforce 'Exceeded max size limit' - agent's REST SOQL returned over 2000 rows without a query locator - ipython-sql result set too large: display truncated, kernel memory spiked
Problem outcome: unknown
Public search query: agent's %%sql query returned 10M rows: OOM in the notebook kernel
Problem outcome: unknown
Fixes Deepnote scheduled runs failing with out-of-memory on a large merge. Use when the scheduled run OOMs but interactive runs survive. Not for kernel or environment install issues.
Fixes marker-pdf OOM on a scanned 500-page contract: split into page-range chunks, convert each separately, concatenate the markdown in order, and tune workers and image extraction. Use when large scans die partway through conversion. Not for install failures or small-file OOMs.
Fixes Node heap exhaustion during jest runs in CI. Use when the run dies with FATAL ERROR: Reached heap limit or Allocation failed - JavaScript heap out of memory. Covers raising the heap with NODE_OPTIONS, cutting worker memory pressure, and finding the leak with open-handle and heap logging. Not for out-of-memory in…
Tunes JVM heap settings to stop Gatling simulations dying with out-of-memory errors. Use when a simulation OOMs under load, especially at peak injection. Not for OOM in the application under test.
Vectle found the following relevant skills: - spark executor "OutOfMemoryError: Java heap space" partition tuning - kernel: TCP: out of memory -- consider tuning tcp_mem": tuning guide
Problem outcome: unknown
Public search query: gatling simulation out of memory: heap tuning
Problem outcome: unknown
Fixes Vitest out-of-memory crashes when the threads pool runs a large suite. Use when workers die with heap errors and the suite is big. Not for OOM in a single test file or for leaks in application code.
Gives agents a playbook for EMR Spark jobs that never finish: Spark UI signals, stuck stages, and bounded waits. Use when an agent waits on a Spark job that stalls. Not for jobs that fail fast.
