Hello all,

I recently upgraded from C* 3.0.10 to 3.0.16 and have been receiving these 
warnings about Commit-Log durations being longer than the configured interval. 
I don't understand what the problem is, why is the system complaining about 
such small sync durations? Please advice.

Here are some warnings:


3:WARN  [PERIODIC-COMMIT-LOG-SYNCER] 2019-03-07 13:32:23,785 
NoSpamLogger.java:94 - Out of 2750 commit log syncs over the past 274s with 
average duration of 0.66ms, 4 have exceeded the configured commit interval by 
an average of 22.50ms



2:WARN  [PERIODIC-COMMIT-LOG-SYNCER] 2019-03-07 13:27:01,214 
NoSpamLogger.java:94 - Out of 1 commit log syncs over the past 0s with average 
duration of 113.00ms, 1 have exceeded the configured commit interval by an 
average of 13.00ms


Node's cassandra.yaml setting related to Commit-Log:

commit_failure_policy: stop
commitlog_directory: /cassandra/log
commitlog_segment_size_in_mb: 32
commitlog_sync: periodic
commitlog_sync_period_in_ms: 10000
commitlog_total_space_in_mb: 4096

Thank you,
Meg Mara
