it is a production server I can not reproduce anymore.
So, once it started it didn't recovered, continued always with that
error? How much of shm did you configure?
You can try to attach from time to time to one process (can be even the
main one to avoid blocking a sip worker) and walk through the shm
allocated chunks, in order to see if there are some unexpected
repetitions of allocation from same place in sources.
I posted the gdb script for walking through pkg at some point, the
difference will be to start from the head of shm list (i.e., starting
with shm_block->first_frag instead of mem_block->first_frag):

You should go as much as possible to the end of the allocated list.
Another option is to add shm_status() (see cfgutils module) in your
config, executed on a special request you can send with
sipsak/udp_flood/sipp . There are other options if you load the cfg_rpc
module and send some rpc commands with sercmd.

Daniel
Sorry

Hello,
sqlops is using pkg and tm shm, so they should not be directly related,
but maybe in the way config file works.
Can you run it again with memlog lower than debug and see where the
allocated (not-freed) chunks were done? It should appear soon, not
waiting for out of mem message.
If you haven't restarted, there is a way to attach with gdb and walk
through shm allocated chunks to spot the occurences.
Cheers,
Daniel

http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users Hi!
I recently had a problem with Kamailio 3.1.4 (provided Debian
packages):
I had some DB problems (missing tables). Thus, the timer module failed
to insert the statistics (for siremis):
ERROR: db_mysql [km_dbase.c:120]: driver error on query: Table
'kamailio.statistics_tmx' doesn't exist
ERROR: <core> [db_query.c:130]: error while submitting query
ERROR: sqlops [sql_api.c:217]: cannot do the query
This happened for some time (weeks?), other DB queries were unaffected.
Then, suddenly Kamailio ran out of memory:
ERROR: <core> [sip_msg_clone.c:506]: ERROR: sip_msg_cloner: cannot
allocate memory
ERROR: tm [t_lookup.c:1338]: ERROR: new_t: out of mem:
ERROR: tm [t_lookup.c:1478]: ERROR: t_newtran: new_t failed
ERROR: sl [sl_funcs.c:282]: ERROR: sl_reply_error used: I'm terribly
sorry, server error occurred (1/SL)
It do not think it is a load problem as the server is more or less
idle. May it be a memory leak due to wrong error handling?
Where there any fixes recently?
Thanks
Klaus
