Yup, many thanks. > Can you break into ddb and do a ps to find out what state all the > processes are in? I'm a newbie to ddb. Was able to get a ps from a hung system but didn't know how to capture it to send to you. Any hints? > You might want to try adding the DEBUG_VFS_LOCKS options to your > kernel config to see if that turns up anything. Oh, man, I'm getting killed here now. Rebuilt the kernel with that option (not found in GENERIC or other examples in /usr/src/sys/i386/conf/). Now the system is dropping into ddb ever minute or so with complaints like the following on the screen, and in /var/log/messages: Jun 17 21:06:08 PECTOPAH kernel: VOP_GETVOBJECT: 0xc584eb68 is not locked but should be Jun 17 21:08:04 PECTOPAH last message repeated 3 times ... Jun 17 21:18:55 PECTOPAH kernel: VOP_GETVOBJECT: 0xc59346d8 is not locked but should be Jun 17 21:18:59 PECTOPAH last message repeated 5 times Lots 'n' lots of 'em, with a few of the same hex value then another set for a different hex value. > There is also ddb command to list the locked vnodes "show > lockedvnods". After I type "cont" at ddb a few times the system runs for a while again, only to repeat. When it drops to ddb again that show command doesn't list anything. I may have to remove that option from my kernel just to get to run a bit, even tho eventually the system will hang. It's (of course) my main box which the other systems NFS off, mail server, etc. :-( > Are you using nullfs or unionfs which are a bit fragile? Nope. I'd be happy to mail you my kernel config if you want. I've posted it to http://chris.shenton.org/PECTOPAH but if the system's hung again, naturally it won't be available :-( Thanks for your help. Any other things I might try? Dunno if this matters, but I'm using an DELL CERC ATA RAID card with disks showing up as amrd* if that matters. Was flawless at 5.0-{CURRENT,RELEASE}.Received on Tue Jun 17 2003 - 16:35:19 UTC
