I have 8.2 amd 64 installed. All was stable until I decided to reload my perl port and picked the old version by mistake. After a couple of frustrating hours, perl was reinstalled and using the various port tools, plus some hard work to pick up modules that the ports system missed, my software all worked correctly.
However, since then the system crashes every hour (there are no cron jobs involved, and I have waited before restarting to see if time of day affects the issue: it doesn't). The error is an ad5 DMA (unable to write error 5). No dump is made,the server says it is unable to do it.
This sounds like it should be a disk problem. Ad5 is not a disk on my machine. There is no ad5 entry in /dev. When the problem first occurred, I thought it might be my disk. I was using two SSDs with gmirror(8) in a RAID 1 config. I tried removing a disk, same problem. I physically substituted another disk. No change. fsck(8) is clean.
I realize this isn't necessarily the OS; though it might be. The problem is that I can't come up with a way to understand the problems. No logs offer anything helpful. The system dies due to the DMA timeouts. That much I am pretty sure is true. One of the port maintainers went through my system and repeated the perl installs. The problem continues and no one has any idea why. I searched on every term I can think of with no success.
I would appreciate any help I can get here.
Thanks,
Bob
