Error while invocking WISD operation

[sujaks]

Hi,

We have a webservice which was running fine from long time. We had some issue in enabling/disabling the service which forced us to re-deploy the service.
After that, the webservice call is getting failed with the below error.

<faultcode>soapenv:Server.generalException</faultcode>

I tried restarting ASBAgent and LoggingAgent but it didnt help. Does anyone come across this issue before?
