[SR-Users] Kamailio Crash when modifying username of Request Uri

[Daniel-Constantin Mierla]

Hello,

you said you saw an increase in memory usage -- was system memory,
right? What was the value, did it exceed shared memory size?

Just to be clear, you run stock kamailio, no patches or other modules
developed in-house?

Cheers,
Daniel
