disregard this. I was incorrect about the source of the
error message. It is coming from a log statement we have
where we are attempting to print the contents of an AVP as a
list. In this case the list is quite long and is causing the
buffer exhaustion.<o:p></o:p></span></p>

this because there does not seem to be any way in OpenSIPS
to determine the number of values in an AVP except to

variable, but avp_insert will not accept a variable as the

using -1 as the index does not work with AVPs.</span><o:p></o:p></span></p>
