After upgrading to Fedora Core 3 (from Fedora Core 1) one of my servers seems to be crashing at least once a month. Running kernel 2.6.11 for a week now the problems doesn't seem to be fixed...

As you can see in the log, there seems to be a problem with the virtual memory:
Apr 22 13:00:06 alpha kernel: EIP is at __rb_rotate_left+0x8/0x3a
The harddisk, however, passed all tests I did. Any suggestions?
Best regards,
