One common problem we see at Reprise is the issue of license servers (especially the ISV server) not starting.  When this happens,  the debug log will look similar to the following:

When this happens, it is usually (99.999% of the time) the fact that another copy of the ISV server is running (in this case “isvabc”).  Use the task manager (on Windows) or “ps -ax” (on Unix) to find the other copy of the server that is running, and, if necessary, kill the old copy (don’t forget to kill the rlm server that started it, too, otherwise that copy of rlm will just re-start the ISV server and you’ll be back to where you started).

Note that a similar situation can occur for rlm itself, if you try to start a new copy of rlm on the same port as another copy.

If you need to run multiple ISV servers (and/or multiple copies of RLM) see the article “Managing Multiple-ISV Installations” here .
