Howdy! I am running 4.3R, on a new server which after being up for 3 days had to be rebooted because of some kind of file/buffer corruption(I think??) After about 10 days I got a wierd read/write error and then by chance I discovered the following in the output of sysctl -a machdep.msgbuf: :53 from 192.168.20.8:2217 <6Connection attempt to UDP 192.168.20.1:53 from 192.168.20.8:2218 <6Connection attempt to UDP 192.168.20.1:53 from 192.168.20.8:2219 [the above is not related to the problem, snip] [the problem ...] sym0:0:control msgout: 80 20 77 d. sym0:0: message c sent on bad reselection.

HOw do I get it into syslog? This is some stuff from dmesg.boot sym0: <1010-33> port 0xe400-0xe4ff mem 0xfebd0000-0xfebd1fff,0xfebd8000-0xfebd83ff irq 3 at device 6.0 on pci1 sym0: Symbios NVRAM, ID 7, Fast-80, LVD, parity checking sym0: open drain IRQ line driver, using on-chip SRAM sym0: using LOAD/STORE-based firmware. sym0: handling phase mismatch from SCRIPTS. sym1: <1010-33> port 0xe800-0xe8ff mem 0xfebf0000-0xfebf1fff,0xfebf8000-0xfebf83ff irq 10 at device 6.1 on pci1 sym1: Symbios NVRAM, ID 7, Fast-80, LVD, parity checking sym1: open drain IRQ line driver, using on-chip SRAM sym1: using LOAD/STORE-based firmware. sym1: handling phase mismatch from SCRIPTS.

Is it OK to have swap starting at the beggining of the disk? # /dev/da0c: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 102400 2097152 4.2BSD 1024 8192 16 # (Cyl. 130*- 136*) b: 2097152 0 swap # (Cyl. 0 - 130*) c: 35860910 0 unused 0 0 # (Cyl. 0 - 2232*) d: 8495534 27365376 4.2BSD 1024 8192 16 # (Cyl. 1703*- 2232*) e: 4194304 2199552 4.2BSD 1024 8192 16 # (Cyl. 136*- 397*) f: 4194304 6393856 4.2BSD 1024 8192 16 # (Cyl. 397*- 659*) g: 2097152 10588160 4.2BSD 1024 8192 16 # (Cyl. 659*- 789*) h: 14680064 12685312 4.2BSD 1024 8192 16 # (Cyl. 789*- 1703*) Any ideas what to check? Hardware issue? I have terminiated the sym0 device in its BIOS and have a terminator on the cable. Bad idea? thanx - steve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
