I've noticed over the past month or so mountd(8) hanging on an NFS server here when the NFS server is running poudriere. This only occurs when poudriere is building multiple little ports resulting in many mounts and unmounts due to jails being constituted and torn down. After a while mountd(8) ends up in a deadlocked state causing poudriere to seize. The workaround is to stop mountd before or immediately following initiation of poudriere. This used to be a problem without the -S flag but now suspend/resume of nfsd threads doesn't mitigate the problem either. Something has changed but I cannot point to any individual commit or group of commits that caused this regression. -- Cheers, Cy Schubert <Cy.Schubert@cschubert.com> FreeBSD UNIX: <cy@FreeBSD.org> Web: https://FreeBSD.org NTP: <cy@nwtime.org> Web: https://nwtime.org e^(i*pi)+1=0help
