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

have you tried the dedicated KEMI functions?<br>

<br>
KSR.x.modf() must be avoided as much as possible, because it
is an<br>
workaround which can also lead to memory leaks if the
kamailio.cfg<br>
functions don't have a free fixup function.<br>
<br>
Cheers,<br>
