One of our FreeBSD servers is locking up intermittently with: Sep 19 15:09:36 foam last message repeated 8 times Sep 19 15:09:36 foam /kernel: (da5:ahc1:0:3:0): SCB 0x1 - timed out while idle, SEQADDR == 0xa Sep 19 15:09:37 foam /kernel: (da5:ahc1:0:3:0): Queuing a BDR SCB Sep 19 15:09:37 foam /kernel: (da5:ahc1:0:3:0): no longer in timeout, status = 34a Sep 19 15:09:40 foam /kernel: (da5:ahc1:0:3:0): Invalidating pack I do not suspect that the drive is losing power and AFAIK (I've checked) the termination on the drives is fine. I'm going to install a new cable/term tommorow just to rule that out however ... Could this be the 'write cache' problem that I have found after doing a search through the archives? If so ... how do I disable write caching with camcontrol? ref: http://www.FreeBSD.org/cgi/getmsg.cgi?fetch=86334+0+/usr/local/www/db/text/2000/freebsd-scsi/20000625.freebsd-scsi also 'top' shows a constant '.8% - 1.2% interrupt' even while the server is idle ... is that normal? (output from top appended) Could this be an indication of some sort of hardware conflict? smbd is an ungodly size because I'm still fighting a memory leak with samba-tng :( thanks, -- Agent Drek Big Animation Inc > 'digital plumber' http://www.bigstudios.com dmesg: Copyright (c) 1992-2000 The FreeBSD Project.
