[SR-Users] Memory issue

[Igor Potjevlesch]

Hello,

 

I had a memory issue this morning.

First, I could see the following logs in /var/log/message :

May 12 11:08:21 localhost /usr/local/sbin/kamailio[30268]: ERROR: <core>

This problem have already occurred and I have set -M 64 to avoid it. It
looks that it's not enough anymore.

What is the next increment recommended after 64M?

 

On the contrary of the first occurrence, Kamailio crash with coredump just
after these errors. I'm not sure that the memory message errors are linked
to the crash. I have tried a "bt full":

(gdb) bt full

#0  db_mysql_store_result (_h=0x7ff44e0e70e0, _r=0x7fffcb00a408) at
km_dbase.c:198

        code = <value optimized out>

        __FUNCTION__ = "db_mysql_store_result"

        ret = <value optimized out>

<db_mysql_submit_query>, 

    store_result=0x7ff44dd93d80 <db_mysql_store_result>) at db_query.c:156

 

Thanks in advance for your help.

 

Regards,

 

Igor.
