Hi,

We are seeing high memory utilization as reported by OS (RHEL). The free memory is shown as <10%. We then go felix console and do a GC. The memory used is decreased. However when we check this agan at OS level then the free memory is not changed at all.

How can this be explained as alerts are set at Linux memory level. 

Thanks,

Anil

Do you run GC using Offline Compaction? Also check the code to make sure there are no open connections you can check that using tools like JMeter. Please refer to performance tuning guidelines for more details.

Thanks
