I'm running freebsd 6.1-release with a customized kernel on amd64 platform.
The motherboard is Tyan Thunder K8S S2882. The board has built-in raid
control, but I use atacontrol instead. The following message will appear
either when there is heavy disk I/O or when system is doing some daily check
up ( for example, security check at 3:00am):
Aug 25 17:34:19 server kernel: DOH! ata_alloc_composite failed!
Aug 25 17:34:19 server kernel: FAILURE - out of memory in
Aug 25 17:34:19 server kernel: g_vfs_done():ar0s1f[WRITE(offset=28373975040,
length=16384)]error = 5
Aug 26 04:15:57 server kernel: DOH! ata_alloc_request failed!
When the error occurs, the system will crash. The console is hangling, it
shutdowns some running application. However, when you ping the server ip
address, it shows the system is still alive. And monitor system shows me
that "total process is in critical situation" ( mean too much process
running at the same time). In such case, I have to reboot the system.
While I was searching the mailing list. I saw a few more people also
encourtered this error. ie, the thread
I am wondering whether someone has figure out what is causing this error and
the way to fix it.
