memory usage is growing after upgrade to zcs 6.014

Hi there, memory usage is growing on ZCS after upgrade to 6.014 from 6.08
The server performance was extremely slow, barely can work with it.
5.5GB of SWAP was in use. We add more RAM to it from 4GB to 16GB

For 12 hours of usage it grow from 4GB to 11.5 GB and it still growing.

Is that how it should be?

   total       used       free     shared    buffers     cached
Mem:         16071      11425       4645          0        313       4445
-/+ buffers/cache:       6666       9404
Swap:        23415          0      23415

Is that a memory leak?
Thank you in advanced for reply.

Best,

Doesn't the highlighted section show zero use of swap or am I missing something? Linux will use RAM for storage in preference to HD.

Have you done any performance tuning? See Performance Tuning Guidelines for Large Deployments - Zimbra :: Wiki.

Thank you for your reply. Yes your right as it's a bit different memory usage then in windows environment.
