Hello Daniel,
Thank you for this feedback.
We are running 4.0.4 without custom module.
I do a sqlops request in a very small table (40 rows) but on each
REGISTER and INVITE.
The bigger table is “aliases” with 154k rows.
Can you highlight me the particular bug concerned and corrected?
In the meantime, for the memory allocation, I have to grow the shared
and/or private memory? What would be the next increment : -M 128?
it doesn't really matter the increment. I think the private memory is
already too big, so if you don't load big amount of data, there could be
a leak.
I backported related patches to branch 4.0 -- you should upgrade to
latest git branch 4.0. In this way you are sure you have all the fixes,
because 4.0.4 is old in the 4.0 branch.
You can use 'kamcmd pkg.stats' to monitor available pkg memory. When you
see the available memory keep decreasing, you can issue:
kam cmd cfg.set_now_int core mem_dump_pkg _PID_
replace PID with an appropriate value you take from pkg.stats. You can
send the output from syslog here for investigation, to see what can be
the potential leak.
If you still have the core file, you can look inside it to see allocated
memory chunks -- see the gdb script at:

Hello,
what version are you using? Are you doing sql queries that return
large number of records (e.g., via sqlops)? Are you using any custom
module you developed?
The crash was fixed in master branch, but somehow forgotten to be
backported -- it is now in branch 4.1.
Cheers,
Daniel

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
