We are running 3.4-RELEASE on a 600mhz AMD machine with 128MB RAM and 2 8GB scsi disks. It runs our mail server, stronghold web server, dns, etc. The machine has been fine since we got it (a hosted machine at rackspace.com) - 0 downtime for about 4 straight moths, until we added a relatively high volume (but by no means crippling) site to it. Since then, the machine panics fairly regulary (sometimes several times a day, other times it may go several days without crashing). With nothing helpful appearing in the dmesg buffer, I finally started doing savecore's and gdb'ing the result to find this: panicstr: rlist_free: free start overlaps already freed area panic messages: --- panic: rlist_free: free start overlaps already freed area syncing disks... 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 giving up [...] I've checked the message archives, and found a similar report but for FreeBSD 3.3. Looking into the source reveals that it is panicing while managing the swap/free space from the best that I can tell. I'm hoping that this is a known problem with FreeBSD 3.x in general and that a fix or some sort of workaround is available. If not, are there pre-emptive measures I can take to avoid this panic? Add more memory? More swap space? I suppose I would also considering upgrading to the latest FreeBSD 4.3 if I could figure out how to upgrade a system remotely while 3.4 is still running (ie not booting from a cd and running some sort of upgrade utility). Any help would be greatly appreciated.
