[Serusers] Memory Problems

Thu Apr 24 12:17:33 CEST 2008

Ricardo,

I raised an issue on the JIRA  [ http://tracker.iptel.org/browse/SER-374?page=all ]. Andrei Pelinescu - Onciul has already put the fix into the 0.9.7, 2.0 and 2.1 branches. You can see the changes using the CVS viewer at http://cvs.berlios.de/cgi-bin/viewcvs.cgi/ser/sip_router/modules/textops/textops.c. I'm guessing that the 0.9.7 development is the branch rel_0_9_0 - hence revision 1.40.2.1. To check this out using cvs you'd need to use the option '-r rel_0_9_0' in your cvs command.

Hi Stuart.
I was about to send another post to ask about this issue.
In fact, i was checking my ser configuration file and i found that i'm using "subst_user" function.

subst_user('/^(.....)(.*)$/\1/');

I'm using the 0.9.7 version.
I will try the solution reported and i will let you know the results I really appreciate you feedback.

One last question, i'm a little bit ignorant about the use of the CVS.  How can i download only the patch you submit?

Thanks again.
Best Regards,
Ricardo Martinez.-

Ricardo,

Are you by any chance using the subst_user function in textops? I'm getting similar symptoms on my servers and I think I've tracked the leak down to this module and wondered if yours is the same problem. I'm using 0.9.6 on Solaris 10 but the source for the textops module hasn't changed between the 2 versions.

Hi Jiri.
Thanks for your answer.
Let me ask one more question.
In the link that you gave me, it said "set adequate memory reporting level in ser configuration file: memlog must be lower than debug (e.g., memlog=2, debug=3)" Is ok with memlog=2 and debug=3? Or i need to add more log level? This is a production machine with a high load.....

I will keep waiting for your comments.
Thanks!!
Ricardo Martinez.-

looks indeed like a memory leak somewhere.
see http://www.iptel.org/ser/problem_reporting
for procedures to spot the problem. (takes recompiling :-(
