[SR-Users] Memory leak in 3.3.4

Hello,
send SIGUSR1 to one of the worker processes (e.g., UDP listener). The
main process of kamailio doesn't process SIP messages, so it is not
exposed to leaks.
You can used 'kamcmd pkg.stats" to see statistics about usage of pkg
per each process (older versions have sercmd).
'kamctl ps' gives the list of processes.
Cheers,
Daniel
