Douglas,
indeed, it looks like there is a a memory leak in using the DNS
resolver. It is used by ENUM module and by the SIP resolver.
So, are you using ENUM module for lookups? Do you have some module of
your own using the DNS resolver?
I took a look into the SIP resolver and I found some possible cases
leading to memory leak, but there were some error handling corner
cases......only if you have some very bogus DNS results...anyhow try to
update from CVS and see if the leak is still present.

Bogdan,
I guess I didn't realise the dumping was done on a per process basis.
I've sent you a complete daemon.log file this time. You will see that many of the
processes are reporting out of memory.
I sent a USR1 signal to pid's 21131, 21127 and 21126 (which where all reporting out of
memory).
Douglas.

Hi Douglas,
I when over the dumps you get, but there is no increasing memory
consumption in time (some number of used mem chunks). Also the first
line shows:
Memory status (pkg):
qm_status (0x8121ba0):
heap size= 1048576
used= 21908, used+overhead=248632, free=799944
so only 25% is used from the 1M available.
Please check that you are actually sending the SIGUSR1 signal to the
process that generated the memory error (it's about the per-process
memory and not the shared one). So, wait for the error to occur, send
the signal to the reporting process and please send me the log (no need
to post again on web).
regards,
bogdan

Bogdan,
I finally managed to upload the memory dumps to pastebin. Links are:
Hopefully you can access them.
Memory dump right after OpenSER was started: http://pastebin.com/723872
Memory dump after OpenSER running for 20min: http://pastebin.com/723890
Memory dump after OpenSER running for 50min: http://pastebin.com/723902
The problem started to occur between the 20 and 50 minute samples. About 20 calls had been
processed in that time.
Douglas.

As written in the wiki, if you do not know how to interpret
the result,
you should post them on a ftp or http server and send the link to the
list - also, important is to mention in which context did you get the
mem dump - is the shutdown dump, a run time dump...

Once I get the memory status, how do I interpret
