high memory usage
 
I have been using ispconfig 3 for quite a while now. Recently, something is not right. Memory usage is hitting up the roof. So I upgraded from 2GB to 8GB yesterday.

This morning when I check the system, I see all the 8GB used up. I feel something is not right. There might be some rogue processes running inside.

I used top to see the memory usage but I can't see anything. Anyone can guide me on checking what is using up all the memory? The "show memory" in ISPconfig is not showing anything useful that I can used.

Here is the top result sorted by memory:

running Munin stats or Piwik or Thinkup ?

had same problem with running them all on the same server :)
Solution is to split them or let Piwik and Thinkup update only once a day not @ the same time!

yes, our developer just install piwik on the server. That was when I notice the load starting to go up. So I upgraded the memory since there are some spare lying around. I did not expect piwik to be taking all the extra memory after upgrade. That's 6GB of extra memory.

Is piwik really that memory hungry program? What can be done to reduce it's memory footprint? It is db internsive or web intensive software?
