Even for checking if all the memory was properly release, you still have to use the Memory debugger - have you managed to get the memory dump on SIGUSR1 (as per example in the page I pointed)? if so, such a dump simply contains a list of all allocated memory chunks - size and where from code they were allocated from.<br>
<br>

Hi Bogdan,<br>
<br>
I checked the method mentioned on the link but really, I am unable to<br>
understand anything generated from the log.<br>
<br>
Now, my problem is not out of memory. I just want to check if there are some<br>
memory which is not *freed*.<br>
<br>
Is there a way I can run opensips with Valgrind, because I am bit<br>
comfortable with it and help is also easily available.<br>
<br>
I am not expert in Unix or OS therefore finding it difficult to understand<br>
the logs.<br>
Hope you understand.<br>
<br>
Thanks,<br>
Surya<br>
