NullPointer on Websphere Performance Tunning Class

[shawn957376]

Hello,

We've started noticing a NullPointerException being thrown on our WebSphere box every 10 seconds:

We're running Websphere on a Linux box. I've looked around the internet but I haven't found anything about any of those classes. Does anyone have an idea of what is causing this. The message is filling up our logs. Thanks in advance.

Shawn,

First it would be nice to have some info.

a)Can you tell me the WebSphere version that you are running?
b)what distr and version of linux is it running on ?
c)in what file do you get this msg ?

Once we know this we might be able to give you a wee hook where to look.
