[-- Attachment #1 --] 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 Alexander@Leidinger.net: PGP 0x8F31830F9F2772BF http://www.FreeBSD.org netchild@FreeBSD.org : PGP 0x8F31830F9F2772BF [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJbA9ItAAoJEKrxQhqFIICEshQP/j9QUdRHfuw9RmAecXXRG40c wy/J1s6I2r1Dzd11HzYSSUo+mWSO+vpPVoIGnI1XBzwDL1HE2LdaJbqB8vT+Spe0 4V6zu8w1ww/52PgWZikzckSGXMsu7/SYnWhVH+RSuzXHVqig7UpR9C+H/4P+/8FM LpqkgHG5T9EHzLc2f3Sun+I8mb+BKJOnW/zlXTt0P7We/cyshFIRfA9fBNTiJKqC hGtDPqp4HJGE5C9u8acmMYNEyNZodSG6F+Najni8j3VZi7fFjF0KZUAKxL+Jvkzn fcoDpvfosoZ5XjxKMMR3jc9W3QemAYKgT77ok893yIr4/9f7e+Nqy2xnrPJIUh39 JKuP8Lmu1hMA3A4xFCgyiAd/IRlo9C2L55QtblPbqKnTf/OyDezAID8L3HUmCLu2 +egklTp3xpt/tAwMnB6of7R3+eFrYmnpzeESnTHT07qrMlysheUpozpC5o6HhsSH lHfAoT/9jWEAvo358OjrGYw9PMuFtA3g+7xemVEevbKah27hBMOWMbMJI6Z1LP4R NVnlFXRyQ5Q/zSP2lgM4rh7Xg5RvadycE+S4srMCjMcYfBVA2isBG3gf4NTre+Kd g7Q837sseQUgYc7wnKu2ASCr5ZKi+rBKiU1ODkeMDaF1b5AlXvG3oKfexQdq7nSh SkErY4XSidwqOGgxkWC9 =87QI -----END PGP SIGNATURE-----home | help
