agent failed to parse Aim query results after repo lock error failed to fetch runs

Not specified by the original author.

TL;DR

Release the repo lock before fetching: the agent failed to parse Aim query results because the underlying fetch hit the locked repo, so coordinate reads with the writing process, or read from a snapshot copy of the repo for analysis. The parse failure is downstream of a storage failure. Aim returned an error or a partial result, and the agent parser reported the symptom it could see.

agent failed to parse Aim query results after repo lock error failed to fetch runs

Use this when

• The check or run fails with this symptom: an agent fails to parse Aim query results after a repo lock error and cannot fetch runs.
• You are working on an agent workflow analysing Aim runs while training jobs write to the same repo and the failure repeats on the same data or configuration.
• You need the failing run, call, or stage isolated before changing code or thresholds.

Not for this skill when

• A repo with no writer that still reports locked, which is the stale lock case needing the lock cleared first.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Reproduce the fetch directly and read the raw response. Verify: the response is a lock error, not run data
2. Identify the process writing to the repo and its expected finish. Verify: the read can be scheduled after the write window
3. For repeated analysis, copy or snapshot the repo and query the copy. Verify: analysis reads succeed while training continues
4. Change the agent to check fetch success and content type before parsing. Verify: a lock error is reported as a lock error
5. Rerun the analysis. Verify: run results parse and summarise normally

Variant phrasings

agent parse aim query results repo lock failed fetch

The shorter phrasing focused on the named failure.

aim repo lock agent fetch runs error

The symptom phrasing a searcher tries next.

aim locked repo agent read fix

The variant naming the failing stage or tool directly.

Compatibility: Aim repository locking, agent analysis workflows over live experiment repos

Why it happens

Agents chain tools assuming each step returns what the next expects. A lock error returned where run data was expected flows into a parser, and the parser error is what gets reported, sending debugging toward file formats instead of the simple contention underneath.

Edge cases / pitfalls

• Validate every fetch by status and shape before parsing; parsers should never be the first place an upstream error is described.
• Read replicas or snapshots are the durable answer for repos under continuous write load.

Evaluate deep nesting as well, keeping Markdown's H6 ceiling a separate constraint rather than requiring a beyond-H6 extension. ## Alternatives Keep explicit paths: deterministic but repeats more ancestry at each level. Flatten headings: reduces repetition by losing useful structure. Automatically reinterpret existing numeric headings: rejected because it changes existing meanings. Relative authoring with full canonical output preserves self-contained citations without requiring authors to duplicate ancestry. ## Why it is worth it Repeated ancestry adds authoring work and another consistency obligation, particularly in deeply nested specifications. Removing it supports friendliness-first and the principle that Grund maintains the knowledge structure. Full canonical addresses preserve precise agent grounding and broken-reference checks. Shorter headings alone are not claimed to reduce retrieval-token costs. Origin: local report grund.24`; triage classified this as a foundational product change, with the prior-policy conflict explicitly accepted for pursuit by the owner.

TL;DR

Stop the other process before blaming corruption: Aim repositories allow one writer at a time, so find the process holding the repo lock, confirm it is finished or stuck, and only open the repo again once the lock is released. Aim locks the repo directory to protect run storage. A crashed or still running tracker leaves the lock held, and every later query fails with the same locked message.

Aim run query failed error "AimRepo: repository is locked by another process"

Use this when

• The check or run fails with this symptom: an Aim run query fails with AimRepo repository is locked by another process.
• You are working on an Aim repository used by training runs and queried from scripts or the Aim UI and the failure repeats on the same data or configuration.
• You need the failing run, call, or stage isolated before changing code or thresholds.

Not for this skill when

• A lock left on a shared filesystem that does not release cleanly, which needs the stale lock cleared after confirming no writer is alive.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Note the process id the lock error or the lock file names. Verify: the holding process is identified
2. Check whether that process is alive and whether it is a live training run or a leftover. Verify: a live writer must finish, a dead one can be cleared
3. If a run is writing, wait for it or query after it ends; do not force the lock. Verify: the lock releases when the writer exits
4. If the holder is dead, remove the stale lock following the Aim repo layout for your version. Verify: the repository opens for a read query
5. Run the original query. Verify: runs return normally

The symptom phrasing a searcher tries next.

aim repo lock stale fix

The variant naming the failing stage or tool directly.

Compatibility: Aim 3.x repositories and lock handling, Aim UI and Python queries

Why it happens

Aim serialises access to a repo with a file lock because run records are appended by training processes while readers query. Crashes, killed jobs, and containers that exit without cleanup all leave the lock behind, and the next reader cannot tell a stale lock from a live writer without checking.

Edge cases / pitfalls

• On network filesystems, lock release can lag after a process dies; verify the holder is gone before clearing anything.
• Two training jobs pointed at one repo will keep colliding; give parallel jobs separate repos or queue their writes.
