I have a number of Web Service activities in several applications.
None of them seems to be working properly.
The Issue:
Once in a while (Approximatelly 20 times a day), the Web Service Invoke operation fails with NullPointerException.
If I try to retry the stalled action, it works. (No need to touch the workflow).
I was guessing that it may be due to database connectivity issues. But actually there are not much open connections with the DB.
This happens throughout the system. (which means on all the applications; even within sub-processes).
I tried to
-> Increase the timeout
-> Embed the WSDL
-> Send Authentications headers
-> Adjust Pooling for the short-lived processes etc. etc.
-> Applied SP1 (9.0.0.1)
But just endup with the same issue.
Any valuable suggestions are much appreciated.
