The system seems to coredump in the operating systems resolver library.

Make sure your DNS configuration is correct and that the given IP is resolvable.

Apart from that I'd check the "analysis" section of the dump, this contains the stack trace and may give a hint where the error is exactly occuring.

Coredumps are caused by program errors and can only be solved by binaries who have a fix for the problem so eventually you won't get around installing new patches.

Hello Reggie,

Please upgrade your kenel patch level to the latest level according to note 19466.

I hope this helps you.

Hi Blanca,

Is there any other workaround rather than upgrading kernel patch level?

Reason is this is a production system and the issue needs to be solved asap...i.e first if there is workaround and next permanents solution by upgrading kernel
