[SR-Users] FW: Regd. t_suspend() and t_continue()

Tue Jan 21 10:08:53 CET 2014

Hello,

if you do:

kamctl mi get_statistics all

do you see an increase of active transactions counter?

Would be possible for you to compile with MEMDBG=1 and then get the 
memory logs?

make MEMDBG=1 cfg

Then add your extra modules in include_modules variable inside modules.lst

Afterwards:

make install

Edit kamailio.cfg and set memlog global parameter to a lower value than 
debug global parameter.

Run kamailio for a while with the new config, when you see the shared 
memory keeps increasing, stop kamailio. Send the log messages from 
syslog to mailing list or made them available for download somewhere.

Cheers,
Daniel
