Memory flush blocks user messages (isCompacting lock)

증상

Memory flush runs as a pre-compaction step that executes an LLM turn. During this time, isCompacting() returns true, which blocks user message queuing. From the user’s perspective, the bot goes silent for the duration of the flush — which can be significant if the session is large.

원인

Agent encountered an unexpected state or unhandled error condition outside the standard error handling path.

해결법

Set softThresholdTokens: 10000 and forceFlushTranscriptBytes: "1MB" to trigger flush earlier when sessions are smaller, reducing flush duration
This reduces but does not eliminate the blocking window
