Hi, does someone else experience deadlocks / hangs in ZFS?
What I see is that if on a 2 socket / 4 cores -> 16 threads system I do a lot in parallel (e.g. updating ports in several jails), then the system may get into a state were I can login, but any exit (e.g. from top) or logout of shell blocks somewhere. Sometimes it helps to CTRL-C all updates to get the system into a good shape again, but most of the times it doesn't.
On another system at the same rev (333966) with a lot less CPUs (and AMD instead of Intel), I don't see such a behavior.
Bye, Alexander. -- http://www.Leidinger.net alexan...@leidinger.net: PGP 0x8F31830F9F2772BF http://www.FreeBSD.org netch...@freebsd.org : PGP 0x8F31830F9F2772BF
