Kurt De Pauw Posted October 4, 2012 Share Posted October 4, 2012 Hello, How much does a normal forum use ? Mine is taking more then 500MB then it go's up to 1250MB and then I need to reboot the server. Can I somwhere limit the usage of memory? Link to comment Share on other sites More sharing options...
Gary. Posted October 4, 2012 Share Posted October 4, 2012 Hello, It may depend on the size of the community and server configuration, It could be a script causing it, Have you set any limits ? Also if you have server access, In SSH type in top and then press ctrl + M, You will see what process is causing the server to use a lot of memory.

Wolfie Posted October 4, 2012 Share Posted October 4, 2012 How much does a normal forum use ? Mine is taking more then 500MB then it go's up to 1250MB and then I need to reboot the server.From a community software only stand point, I have to ask, how many forums do you have on just the one site? How many visitors at a time? What's the CPU usage looking like?Also if you have server access, In SSH type in top and then press ctrl + M, You will see what process is causing the server to use a lot of memory.Here's a little secret, but don't tell anyone. After typing 'top', you can press the Enter key instead of holding down the ctrl key and pressing M. ;) Link to comment Share on other sites More sharing options...
Kurt De Pauw Posted October 5, 2012 Author Share Posted October 5, 2012 30 users 900 bot connections CPU usage : peaks between 45% and 75% from apache and my username of the forum (httpd) Mem usage : between 2 and 4% from the above users php max usage is 128MB Link to comment Share on other sites More sharing options...
Grumpy Posted October 5, 2012 Share Posted October 5, 2012 Why are there only maximum of 4 httpd processes? Do you have a proxy or another handler in front like nginx? You will likely benefit heavily from increasing max child count of httpd. You may be getting bogged down due to low process count. This will actually increase potential memory usage, but faster handling will, in the end, lower it. If you have problematic bot connections, it'll also be worthwhile to ban them via firewall. You can also opt for less memory hogging alternatives like nginx+php-fpm. Do you have a control panel? The memory usage doesn't really seem to add up... Given your httpd, highest one uses like 3%.

Kurt De Pauw Posted October 5, 2012 Author Share Posted October 5, 2012 I have more httpd processes ( a few minutes ago i had 12 of them ) where can I increase max child count of httpd ?For the moment the site is stable on 50% of its memory Link to comment Share on other sites More sharing options...
Grumpy Posted October 6, 2012 Share Posted October 6, 2012 If you have bunch of idling httpd processes or a higher limit already, ignore my recommendation. It wouldn't help you, only make it worse. You can find the max child in apache configuration. Where exactly, I cannot tell you since I don't know your system. And frankly, I cannot realistically assist further either as you haven't really given enough information. Link to comment Share on other sites More sharing options...
Rhett Posted October 6, 2012 Share Posted October 6, 2012 With the number of connections you have stated only using 750mb of memory is actually pretty low, keep in mind linux will use most of the memory available for many items/processes, typically if you have 2gb installed, if setup properly, you will use 98% of this 2gb of memory. It's nothing to worry about however as linux memory management will allocate memory where it's needed. Are you seeing a problem with performance or just looking for one?

Kurt De Pauw Posted October 6, 2012 Author Share Posted October 6, 2012 We have a performance issue because sometimes CPU and MEM is peaking to 120% and then server stops responding. I will upgrade with another 1GB memory Link to comment Share on other sites More sharing options...
