Hi Grant,
for clarification -- using the dedicated KEMI function is working fine? Only when using x.modf() is crashing?
Cheers, Daniel

Hi Daniel,
Yes, I’ve only been using the dedicated KEMI functions. This was just a simple try to see what would happen. Anyways, thanks for the tip!

Hello, have you tried the dedicated KEMI functions? - http://kamailio.org/docs/tutorials/devel/kamailio-kemi-framework/modules/#auth_ephemeral KSR.x.modf() must be avoided as much as possible, because it is an workaround which can also lead to memory leaks if the kamailio.cfg functions don't have a free fixup function.
