annotate src/core/ngx_murmurhash.h @ 7002:ab199f0eb8e8
Cache: ignore long locked entries during forced expire.
Abnormally exited workers may leave locked cache entries, this can
result in the cache size on disk exceeding max_size and shared memory
exhaustion.
This change mitigates the issue by ignoring locked entries during forced
expire. It also increases the visibility of the problem by logging such
entries.
