Problem description / Issue description
ThinkServer Java System i Server service crashes and iSeries monitor’s agents stops working.
When trying to start the service again you receive and error stating that only one usage of each socket address is permitted or that the service failed to start for an unknown issue. If you check the status of ports, netstat shows that the configured port is already taken by a dead process that should have been completely closed by the stopped service.
Unable to start service ThinkServer Java System i Server, receiving the following message:
Error starting Thinkserver. Error: Communications error.
Fault: Only one usage of each socket address (protocol/network address/port) is normally permitted.
This is caused by an OS limitation, for some reason the process doesn’t finishes properly when the service crashes and the port configured in l2config.cfg remains occupied by that hanged process.
Reboot the server.
