Hi Bobby,<br><br>Your backtrace was very helpful: it looked exactly like one I got several months ago! 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>
