ZCS 7.1.3 consumed a lot of memory (all system memory)

Postby soba@ukw.edu.pl » Wed Dec 07, 2011 12:23 pm

Hi i use ZCS 7.1.3 with SLES 11 SP1.
After a period of 21 days, the system is busy the entire RAM – 60 GB
I add new 60 GB to VMWare. Now I have 120 GB RAM.

After a period of 40 days ZCS consumed all of 120 GB RAM and use SWAP space!


Memory is not released in the system. Does anyone have a similar problem?

Have you checked what is consuming all the memory? My best guess would be Java.
PS: If you have a program or server consuming all the memory all of a sudden, its usually not a case of throw more memory/money at it. Logs and stats are your best friends with these sorts of issues.

Yes - this is probably java problem, but when I shut down the ZCS application, my SLES doesn't refreash usage memory. I still have all memory in use...

Are you experiencing performance issues? Those values do not seem bad to me. Lots of cache and inactive memory, which is normal. The OS will manage the memory properly even when process have finished.

Hi - about cached memory - this is a LVM (disc) problem.

I moved all /opt/zimbra data to normal (not LVM) reiserfs partition.


We can also use flush memory cached procedure.
