Shows SAP connectivity being timed out from SAP side.

I have also read transmitter log and could not find any issues related to agent contacting AE server.

From logs it proves it gets timed out from SAP Server side.

Please see if you applied patch RO98357.

Below is the fixed issue from plugin.

10.Problem 30-Threads getting blocked when sap
throws timeout error.

If not solution is to apply RO98357 and do reply so i will attach the patch to this case.

set below parameter

sap.connection.wait.sec
Specifies the time in seconds that the persistent connection pool must be empty before the agent plug-in either uses or replaces a connection.
For example,if sap.connection.wait.sec =100, when the connection pool is empty to process a request, it waits for 100 seconds to get the connection. If the connection is available within 100 seconds, the connection is used. If the connection is not available for 100 seconds then the connection is replaced.

The number can be set in seconds.
