Scylla try to stop view builder even if it is disabled, resulting in a core dump #4589
Time Window Compaction Strategy: on some very rare cases, a use after free may hurt performance #4465
Stability: In some cases, when --abort-on-lsa-bad-alloc is enabled, Scylla aborts even though it’s not really out of memory #2924
