Hello,

In the last two days i have beed experiencing abends in module NWUTIL.NLM...

We are using two clustered dl380 with nw6 sp5.
Server A had an abend with module NWUTIL.
Next day, Server B experienced the same abend.
Nothing to my knowledge has changed in this environment.

Have any hints ?


Thank you.

Here are the two abends :

Server A :
