Hello team,

I am observing below warn and info message in system.log

1. Info log: maximum memory usage reached (1.000GiB), cannot allocate chunk
of 1 MiB.

I tried by increasing the file_cache_size_in_mb in Cassandra.yaml from 512
to 1024. But still this message shows up in logs.

2. Warn log: Out of 25 commit log syncs over the past 223 second with
average duration of 36.28 ms, 2 have exceeded the configured commit
interval by an average of 200.44ms

Commitlog sync is periodic
Commitlog_sync_period_in_ms is set to 10 seconds
Commitlog_segment_size_in_mb is set to 32
Commitlog_total_size_in_mb is set to 1024

Kindly comment on what may I conclude from above logs
