FreeBSD 6.2-RC1 #1: Sun Dec 10 12:34:12 EET 2006 root@...:/usr/obj/usr/src/sys/SMP Nov 24 00:18:44 sh kernel: swap_pager: indefinite wait buffer: bufobj: 0, blkno: 160, size: 4096 Nov 24 00:21:43 sh kernel: swap_pager: indefinite wait buffer: bufobj: 0, blkno: 160, size: 4096 # swapinfo Device 1K-blocks Used Avail Capacity /dev/amrd0s1b 1048576 884 1047692 0% so, you are not alone ;) only our server recovers after 1 or 2 minutes. Previously it was running 6.1-STABLE, now it's 6.2-RC1 and so far so good, but that's probably only temporary. BTW, before we used megarc for monitoring (through nagios each 5 minutes), now amrstat each 15 minutes. # amrstat -g Product <Intel(R) RAID Controller SRCZCRX> Firmware 414D BIOS H431 SCSI channels 2 Fibre loops 0 Memory size 128 MB Battery status not present, charge unknown Logical volume 0 optimal (339.93 GB, RAID5) Physical drive 0:0 online Physical drive 0:1 online Physical drive 0:2 online Physical drive 0:3 online Physical drive 0:4 online Physical drive 0:5 online Paulius
