OpenKM Server is using too much memory
PostPosted:Mon Sep 21, 2020 12:04 pm
Hi guys
I'm using OpenKM 6.3 community edition with MySQL database
My repository of files consists of about 22000 documents which have taken about 42 GB spaces on hard dick.
I have installed OpenKM on a Debian Linux server with 24 GB of rams and OpenKM (with its requirement like JRE, MySQL,...) is the only system which has been installed on the server (no more software or system has been installed)
A few days ago I felt OpenKM is running a little slow, so I've checked the server resources and to my surprise, I saw that the 23 GB from the 24 GB of server ram has been taken.
Today I checked it again and it was reduced to 13 GB but I think this is still a little unusual because in this situation java at most uses 18 percent of ram and about 1 percent for MySQL.(I have set the maximum ram of tomcat on 4048 MB). It means both MySQL and java should use 19 percent = 4.45 GB of memory. So who is using the rest of Ram? Does the Debian operation system itself may use up to 18 GB of rams while it even has no graphical user interface.
I have provided some screenshots of the situation. Would you please help me to find out what is going on in the server?
