Can you bisect ? I looked over the stated range and I do not see a revision that would be an obvious candidate for the regression. I could think about r345955, r345980, and r345982/r345983 as something that might be most interesting to try. > When launching "poudriere bulk -a", the ssh session is terminated > when poudriere attempts to clone/start builders (tmpfs mounts, file > copying...), the jails don't start and the consequence is that we > can't build any package. Are there any more details about the issue ? It is not clear, does the machine survives the event, i.e. did kernel paniced, what are the console messages, any more details that you can provide. Long time ago there was a similarly sound bug where mountd(8) signalled wrong process, which caused ssh sessions termination. > > Cheers, > > Antoine (with hat: portmgr)
