[Savannah-hackers] Savannah overload issues

[Vincent Caron]

Hello,

  some people might have noticed we have had some ponctual troubles on 
Savannah since a week. It just happened again (around 5pm EST). I will 
now actively try to track the problem and also install some preventive 
measures.

  Technically, a CVS process launched from xinetd and doing a regular 
anonymous checkout with Unix account anoncvs is allocating memory 
forever (claiming 600-800MB out of 1GB physical). Apache and MySQL, in 
dire of memory, start to swap frantically and basically everything stop 
responding.

  I did not think about stracing it before killing it, and since all 
useful info travel through the pserver protocol, I don't have much info. 
I'll try to correlate the process start time with the CVS project 
histories. I suggest the next admin running in this kind of trouble does 
the following :

 - find the top memory consumer: ps -afux -O-r|head
 - trace it a few minutes      : strace -p <pid> 2>cvs.strace (Ctrl+C 
to end)
 - 'fix' the immediate pb      : kill -9 <pid>
 - notify me :)

Thanks for your attention...
