Recently upgraded to Automate Plus/Ultimate 11.3.10 and the agents are continuing to disconnect randomly.

Possibly this is due to a task with some bad code, but I am having issues narrowing down which task. There are no errors in Event Viewer.

Searching the database, I see the following errors:

        Task 'Alert - FO - ADS/CMRI Downloader Stale Data - Alert' did not start because: agent communication failed..

With result code 2 and 14. Usually this occurs for 2 servers at a time, affecting a large number of jobs. We have 6 servers with agents installed.

Wasn't this error supposed to be corrected in this release or is this a new Agent disconnect issue?


Release notes:
[24407] Agent disconnection due to the reported "HandleChannelDisconnect" error is now resolved

This seems to be a new issue, probably due to the new way that the agents are communicating back to the Execution Server.

Any update on this issue? Just recently got one of my task failed due to this error 'communication failed'. I'm using 11.1.30 version.

Hello Rommel,

The HandleChannelDisconnect issue has been resolved in 11.3. It is recommended to upgrade to this version for the permanent fix.

Still working with the support team on narrowing down the root cause via debug dlls and event logs.

This issue hasn't been resolved. I am still encountering this issue and am still working with the support team on narrowing down the root cause via debug DLLs and event logs.

Hello Ludik,

Understood. We will continue working with you via the support case.

Thanks. Hopefully will keep this thread updated. We are evaluating to upgrade our version from 11.1.30 to 11.3 but if 11.3 version has this error I supposed it would be risky to upgrade. 

I saw a new release 11.4 but it does have any fixes related to task agent.
