Tar and webalizer keeps running at high cpu usage

Hi,

I have a weird problem, sometimes tar and/or webalizer keeps running at nearly 100% cpu usage (so it doesn't stop when the process should be done, I have to kill it).

Sometimes this starts with the nightly tally, sometimes it starts when some user makes a backup of his site.

Anyone else experiencing this problem and/or know a possible fix?

Yes I've got the same problem with fullbackup with sysbk. This process just keeps hanging if TAR is hanging.

Not at 100%, but After a few weeks I've got plenty of "Ghost" processes (Defunc)

I've solved this by issueing a "killall sysbk -9" at a time i'm sure it should be done in cron. But if it uses 100% of you're processor. You should check out where it is hanging :s

I can't find out what's actually causing it. Webalizer is looping now nightly and it's not always the same domain which it's processing when it starts to loop.

I also get every night a mail from dataskq which contains: "Abort trap" which is probably a signal 6.

Any idea what I should be looking for?
