6.7.2 External Task Error

foogoo

I am having problem with all the workflows randomly at external Tasks in various places. Sometimes I can go through the whole workflow without encountering any problem. However sometime the workflow stops at the external task. These workflows were fine a week ago and the code hasn’t been changed. Only the system has been upgraded from 6.7.1 to 6.7.2 Service Pack 2 months ago and we haven’t noticed this problem at the beginning, only recently this problem arose on all the workflows. It is hard to debug since the error is occurring randomly at different task.


The error messages:

servletd_out.log

com.interwoven.ui.base.impl.auth.AuthenticationFilter () - Cannot create AuthenticationContext
java.lang.NullPointerException

error.log
Workflow object 4314845 does not exist.

Sometime the servletd_out.log throws full stack trace error description
