X-BeenThere: freebsd-jail@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: "Discussion about FreeBSD jail\(8\)" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 16 Nov 2008 04:27:50 -0000 Hi all, I've been experiencing problems with one of the machines running FreeBSD 7.1-PRERELEASE #2: Thu Oct 16 20:23:09 CEST 2008 with the multi-ip patch bz_jail7-20080920-01-at150161.diff, and I'm wondering if it possibly related to the patch - in any case, any advice would be very welcome. It happens that mysql (tried both 4.0 and 5.1, in 2 separate jails), at some time stop responding to connections, and mysql gets stuck in sbwait state. It is only killable with kill -9 each of the two mysqlds is running in a jail on one private IP, serving connections to a webserver nearby - the latter having one public and one private IP, communicating with the other jail via the private network. I also experienced two complete system hangs (which must not be necessarily related to the mysql problem) both during a shutdown -r now. one was a panic, in another case the machine was still pingable but did not shut down completely. I could only reset it over the DRAC. here's a screenshot I made over the Dell RAC: http://lorenzo.yellowspace.net/stuck.png Since I'm also using zfs there and the kernel has been built with the DTRACE options. any advice (also about which more details that I should/could provide) would be very welcome... thanx && regards, Lorenzo
