Excellent, thanks for the info and the fix!<div><br></div><div>I've applied this patch to a development machine and tested with the signaling capture that got us into this scenario, and it seems to be fixed. To the rest of the community, is there any way we can get this verified and applied to trunk before the 1.6.4 release that's coming up soon? It's one of those situations where we're hesitant to ride on a non GA'd release, and there are some feature enhancements around acc and dialog tracking for cdr's that I'd really like to pull off of trunk for the next official release.<br>

It is caused by an un-initialized field when tm clones into shared memory. I uploaded patch under ID <span><strong>3047314 </strong></span>back in Sep. See the 1st comment and the 1st patch file. The patch hasn't been accepted, probably because it is lumped together with a feature enhancement.<br>
