Thanks for this information. Unfortunately my current kernel was built without CONFIG_KALLSYMS. I'm now recompiling with CONFIG_KALLSYMS and CONFIG_KALLSYMS_ALL set. I reckon that my old traces can't be ksymoops'ed even if i enable that kernel option now? I will see if i can get a fresh trace then (even though i hope it won't happen again).Also when you next rebuilt the kernel please make sure to include CONFIG_KALLSYMS in the configuration, possibly CONFIG_KALLSYMS_ALL too. This will help greatly with decoding any kind of warning / oops.
Unfortunately everything in the logs is dandy until the error happens. It seems that xfs_fsr randomly stops at some files and then locks up the whole /var partition. I searched for the inode numbers where xfs_fsr stopped and one time it was "/var/log/xfs_fsr.log" and the other time it was "/var/spool/imap/x/user/xxxx/cyrus.cache" (username obfuscated). Whats's interesting is that i have the no-defrag flag set on the whole /var/log directory and still it seemed to hang on that log file.Was there anything else in the logs prior to the oops messages that might indicate errors were occurring?
