Hi all,

I ran a random test. After a while, I got the below error and the TC server dies.

Could you tell me what this message mean and why am I getting this message? Thank you, Grace

Can you share the full server and client log please ?

Hi,

I attached a shorten version of the logs from the point when the issue occurred. Sorry, if you really need the entire logs, I will see what I can do. Let me know.

Thanks.

I have created a Jira to track this.

https://jira.terracotta.org/jira/browse/CDV-1563

If you have a reproducible test case, please add it to the jira.

This problem should be fixed in trunk and 3.5 line. The next release 3.5.2 should contain the fix.

The Jira mentions "workaround available". We've just had a production failure with this error. What's the workaround?

edit: thanks for the response ssubbiah, unfortunately we are using web sessions

The workaround is to run all your distributed Ehcache in "DCV2" mode and not in "classic" mode. The work around is only available for distributed Ehcache usecase.
