Hi !
I'm experiencing a major problem since installing version zcs-8.7.11_GA_1854 on UBUNTU 16 64 bit
When I start the zimbra, it already allocates 3.5 GB and during the day continues to increase the used memory. My server had 8 GB of memory and I recently upgraded to 16 GB of RAM. I currently have approximately 250 active accounts. The available memory goes down gradually, and when it finishes the load aveage arrives at very high levels and it catches the whole server.
In rare moments, free and available memory increases.
Below the output commands:
free -m
total used free shared buff / cache available
Mem: 15760 7287 3991 160 4481 8007
Swap: 1953 0 1953
ps -A --sort -rss -o comm,pmem,pcpu | head -n 20

Any help is welcome to stabilize my server !

Re: Zimbra 8.7.11 eating all free / available memory
What is Java heap size and innodb buffer pool size set in your environment?

Re: Zimbra 8.7.11 eating all free / available memory
As Raun said, check your heap and innodb buffer pool size. Have you upgraded to 28 GB or 28 was the size at installation time?
