Have you tried running netstat to see if that port is active? That might be a good place to start.

Dear Mega,

Hope you are doing good.

Please do the following:

1) increase MAXUSERTASKS to the sufficient value

2) apply latest MaxDB patch.

3) check if ALL MAXDB parameters are configured according SAP note 814704.

4) check how many connection have been configured for the java-connection pool and how the database had been set up:

Sap note: 757914 - -9807 Task Limit

Then do a complete restart.

Thank you and have a nice day :).
