[SOLVED] Error when opening report in Excel

[kc9400]

When trying to open a report in excel I get one of the following error messages:

The absolute affinity request 'asynchWait_Request' failed, the requested session does not exist.

DPR-ERR-2082 An error has occurred. Please contact your administrator. The complete error has been logged by CAF with SecureErrorID:2013-07-24-06:40:01.343-#91
Or

Exception occurred: java.lang.NullPointerException


Does anyone have any advice or any ideas as to somewhere I could look to resolve this issue.

I have resolved this issue by restarting the server. I'm not sure if that counts as a fix or not.

Anyway it seems that something was hogging a lot of resources and making cognos stop working.
