Ever since a powercut last night Java has been running at between
approx. 80 and 130% CPU usage. Restarts, logging into other accounts,
quitting the Java process, closing all apps - none of it helps.

I'm on a mid-2007 24" 2.8GHz iMac running 10.5.8. Any advice beyond
reinstalling OSX which I'm not keen on? I have backups of everything of
course.

TIA,
Jamie Kahn Genet

I think I would try to find out what is launching the Java application
to begin with. It's obviously something that starts up no matter what.
Does a "ps -ax" listing show the entire Java command line? You might
also take a look in the "lsof" listing to see if you see any Java
applets open.

Turned out to be CrashPlan - I'd forgotten it was Java until this
morning. It's backup was damaged somehow in the above incident and it
was reacting badly. Clearly no timeouts or sanity checking there *cross
look* Uninstalling and reinstalling it solved the CPU usage issue, but
it refuses to recognise the archive - just gives (CrashPlan) system
errors or says it's not accessible.

It _is_ the first time in two years that CrashPlan's let me down, but
still frustrating. I'm waiting on a reply from their support, but fear I
may have lost over 22GBs of backed up, encrypted and compressed (so not
easily recoverable) data from a remote machine. *groans at the thought
of how long that will take to transfer again across the 'net* I hope I'm
wrong and the system is a tad more resilient than that. Wish me luck JR!
