Hi Alex, yes, avp should be persistent. I've never seen a crash like this in 5.2.x (the release I'm using in prod) and I'm using avp in resume routes, even suspending/resuming twice a single transaction (I have a scenario where two http queries are run). Have anything changed in your system recently, e.g. libcurl version? I'll try to have a look in the next days to what might have changed in the transactions framework that could explain.
