What
This PR resolves #14310 and #14311 by replacing all "infinite" cache lifetimes and cleaning up
MemoryKVCache<T>. Expiration lifetimes of all memory / redis caches have been reset to a reasonable number and normalized between similar caches.Redis caches have a synchronization fix, and an optimization is applied to
MemoryKVCache.gc().Why
The linked issues pose a serious reliability issue that is affecting many instances, including my own. Resolving the memory leaks will improve stability, uptime, and performance.
Fix #14310
Fix #14311
Additional info (optional)
This change is upstreamed from the Sharkey fork. Please see Sharkey MR #580 for additional details and context.
This replaces #14314, which was an earlier attempt at a similar fix.
