Hallo, I have investigated the crash a bit further. I have added decref/incref trace printout and I got the following at the moment of crash:

Transport object 0xbc1430 seems to have been deleted when event 0xbcddb0 for pn_connection was destroyed. But next event popped for the collector refers to the same transport (0xbc1430, already destroyed). Any suggestions how to fix this or speed the investigation up? best regards, -- \ / | | (OvO) | Mikhail Iwanow | (^^^) | | \^/ | E-mail: iv...@logit-ag.de | ^ ^ | |
