MID Server Did Not Get A Response

I have two (2) MID server services run on a Windows 2012 server 1) one for Prod and 2) one for Dev.   Both these were working last week.   Both are same version.   Both MID servers are up and running.   When I do a test load in Prod it works.   When I run the exact same data source "Load 20 Test Records" in Dev, it fails.   I get the following error saying "Did not get a response from the MID server".

Log in agent\logs:

I've tried everything from restarting the server, deleting and rebuilding MID server and still no luck.   Any help would be greatly appreciated.

Thanks.

what kind of Data Load Operation you are trying to perform using this Mid-Server ? and your Mid-Server status is Up ?


MID Server is up and validated.   I'm just trying to do a simple JDBC sql statement.   It works in Prod but does not Dev.   MID Server service is on the same box.   This use to work last week.


Found few links. They maybe of Help. Seems like this issue is more likely due to hanged ECC queue entry which then freeze thw working of Mid-Server. Cancel the running ECC entries and restarting the Mid-Server may resolve this issue. Are you in Helsinki ? Look for PRB665835 in (Helsinki Patch 4 )

Rajeev.   You are correct.   PRB665835 workaround was successful.
