Something isn't working
--cache_mode=true
#3155
Describe the bug
Dragonfly fails with OOM even when
--cache_mode=true
. This happens after multiple hours/days of intense load.To Reproduce
We noticed this on several services that were processing ~200k commands/s and which had between 11k and 15k clients. Also, at the time of the OOM restart, the RSS memory was 162GB, while the used memory was 128GB.
Expected behavior
Dragonfly shouldn't crash.
