Hello Dennis.

As always thanks for your help.

Here is the output of the commands you told me to run.

I keep seing /usr/lib/libc.2 a lot..... I checked and there is a new patch available.

I checked another server that has the same patch as this one and ignite is working on that server, the only diference I see is that server that is working has BASE and QTY. patches from 2006.

The one that is failing has BASE and QTY. from 2004, could this be related in any way ?

>Here is the output of the commands you told me to run.

This indicates you have heap corruption, it is dying after free is called.

0xc0197998 : ldw 0xc(%r26),%r31 < abort here
arg0/r26: 8210681

The value in R26 is misaligned and doesn't have the high nibble set.

>The one that is failing has BASE and QTY from 2004, could this be related in any way?

Yes.

Hello guys.
Management allowed me to patch the system, but until december so I will update this thread until then.


thanks for your help.

I know this is an old thread, but i stumpled about it due to the fact i have the same problem on several machines since last week.

Answer on my call was "known issue" with that specific version.

Check
http://www.itrc.hp.com/service/cki/docDisplay.do?docId=QXCR1000978239
for details.

As well in the meantime 7.9.261 is available and in the release notes (http://www.docs.hp.com/en/5992-5168/5992-5168.pdf) you can find:

"An array out-of-bounds memory corruption defect in
make_net_recovery and make_tape_recovery introduced"

Hopefully this will save you the time to update the box.

I'm going to install 7.9.261 right now and test if the problem is gone.

[Luitzen]

Hi,

just installed C.7.9.261, PAX-ENH and PHCO_39677 and for me it works now!

Kind regards, Luitzen

[Stephan.]

Confirmed, works even without any patches on a box from 2004 :-x

have fun,

Stephan

Hello svo, Luitzen.

Thanks for the reply.

I'll try out your suggestions and install the new ignite version.

I hope this solves this problem.

The only thing I had left to do on that server was to hit it with a baseball bat, :S

I'll post the results. later on the day.

[Fabian Briseño]

Hello, Luitzen, svo.

Installing the latest ignite software version corrected the problem.

Just finished running an ignite backup on the troubled server.

Thanks a lot to everybody, you all were a great help.

Now I have to update ignite software on all clients, but that no problem.

Drinks are on me guys, ;)
