Re: [SR-Users] Memory leak in 3.3.4

11 Oct 2013

Hi Daniel,

Thanks for the reply. Perhaps what we're seeing is normal, and the memory
use is meant to increase as time progresses. Would you expect to see an
ongoing memory use increase, or when should it stop increasing?

  Hi Daniel,

  I was looking to give you the information you requested in your previous
 reply for PID 6824. Hopefully this is it:

 # sercmd pkg.stats pid 6824
 {
     entry: 1
     pid: 6824
     rank: 1
     used: 209836
     free: 3704080
     real_used: 490224
 }

 used memory is like 200k out of 4MB, so it is not big and the log you sent
 with memory chunks didn't reveal a potential leaking. Maybe it is a corner
 case not hit so far.

 You need to monitor for a while and when you see that used memory value
 has increased with few more 100k (or getting at 1MB) and doesn't go back
 low, then dump again the log with memory chunks and sent it over.

 Cheers,
 Daniel

   Hello,

 getting pkg stats for a process:

 sercmd pkg.stats pid 1234

 replace 1234 with the real PID value. There are options to use rank or
 index, see:

 - http://kamailio.org/docs/modules/stable/modules/kex.html#idp213872

 Is it what you were looking for or did I misunderstood?

 Cheers,
 Daniel

  Hi Daniel,

  How do I get that information please? The information above includes
 what I got from the pkgstats module. Is it by restarting Kamailio?

   Hello,

 none of the chunks there are indication of a leak. Can you give the
 output of pkg.stats for pid 6824? Which of the processes has the highest
 value of used pkg memory?

 Cheers,
 Daniel

 Hi Daniel,

  Here are the 'kamctl ps' and pkg status logs. During the 24 hours it
 ran for lots of REGISTER packets came through and memory use definitely
 increased. Thank you.
