I had got the same problem with Apache= + ZFS combination (but it was an old FreeBSD version like 7-8, I don't reme= mber). The main point is that the process hangs in iowait state, which it ne= ver will exit from. The only solution is hard reboot. The reason of that is r= ather more complicated, than just "NFS is bad", or "Apache is bad". This is a= n Open Source, and you could always help with a patch, extensive debug info t= o clarify the bug, etc, so any help will be appreciated. > On 9 Aug 2019, at 23:29, hw wrote: >=20 > Graham Perrin writes: >=20 >>> On 08/08/2019 17:05, hw wrote: >>> =85 Firefox has a tendency to become unresponsive. =85 >> Which version of the OS? >=20 > 12 release >=20 > It turned out that Firefox was stuck in some kind of NFS deadlock.
