Try restarting MPP and EPM then.

Hi,

There were more posts on Stackunsynchronized Error. But didn't find any root cause or exact solution for this.

Could you please help me to find exact root cause and solution for this type of error.

Make sure you tracing is enables. then in the main application you will find a trace.log file in webapps/<appname/data/log.

Post that file.>

Hello
We have the same problem in our EP 7 using Tomcat 7.

What can be the problem?

Can you post the app trace.log?

Hi,
We attached the trace and STDOUT files where the StackUnsynchronized.peek(StackUnsynchronized.java error occurs for the session 1488889FCDFE88BF7F5D24780D112C5D(blmpp1-2017275065035-43)

Thank you in advance for your help.
Anna

I can't open the 2g log file in a regular text editor. Don't you find any log file in the data/log directory of the app? The error in the other text file says java.lang.NullPointerException different from what you previously saw. However the exception does not have the stack trace thus I can't see exactly where it happens.

I used split on the 2 gb file but there is nothing of use in there. can you post the original file that the Document3.txt was derrived from.

Hi
Please find attached ZIP file

Thank you
Anna

My main recommentation would be to not use so many local calls (or any). The release notes have been ammended to say only use local call if absolutely necesary. It looks like things go arwy when there is a disconnect and you are several levels deep in local calls with no interveining (inbetween) vxml pages being generated.
