One of our cluster server nodes has abended and restarted 3 times in 3 days, the abends were in different nlms, apache2 & java, which may be related. I've looked at the apache logs but can't see anything that looks like its caused the problem.

The volume which it supports has failed over to another node which has not experienced any problems since. I haven't migrated it back the last time.

Abend log attached, (the first abend didn't write anything to the log, so only 2 abends shown)

Any help/ideas would be appreciated.
