Hi,

Past week I had an incident with one of our production boxes. The box stopped responding and the console lots of SCSI errors, after rebooting the box since it was unresponsive even through local console, I examined the logs and the following errors showed up:

2 minutes forward in the log file the message repeated up all over again, this situation kept repeating over and over again until the box crashed and I manually rebooted it.
After the reboot the problem didn't showed up again, so I thought that it was an isolated incident, but last night it happened again, and the funny thing is, it happened over other disk (this time the error starts with (da2:ahc0:0:2:0): SCB 0x0 - timed out) ), so I'm starting to think that it's probably not a a disk failure issue.
It is important to note that at the moment of the crash, the box was under heavy load (delivering more that 100Mb/s from the disks to the network)

the dmesg of the box is the following:

I'm pretty lost over the SCSI area, so if anyone can lend me a hand I would greatly appreciate it.
If any additional information is needed to debug the problem I can provide it.

Thanks in advance.

Best Regards,

Luis
