I woke up to a frozen box this morning - it froze up a few more times before I got a handle on it. Basically, the box runs idle but refuses to do disk IO, or does it -very- slowly. Top shows processes stuck in 'ffsvget', 'inode', and 'vlruwk' state. I can get the box responsive again by setting sysctl kern.maxvnods=100000. It starts up with kern.maxnodes=36079. I don't know yet if this is a 'fix' - I wanted to send this mail out before the box froze again. I can reliably get the box in to this state by doing 'find /'. I do have a lot of files on the disk, and a things like squid and postgres that do a lot of file i/o, but I don't recall this happening before this week. I don't find anything in 'tuning' about bumping up vnodes, but I do see sporadic reports on a google group search - searching for 'ffsvgt'. Anybody run into this before? - Mike H.
