CAUSE:
The code for logging users into the database was changed slightly for 8.3A, with the intention of optimizing it. However, this unfortunately introduced some bugs. Under certain circumstances, the changes meant that the login semaphore was locked, and if a subsequent error occurred, it was not unlocked.
FIX:
Upgrade to Progress 8.3C or 9.0C or 9.1A or later.
Shutting down the database and restarting it will resolve this problem only temporarily (the shared memory and semaphores are removed on shutdown).
A workaround is to increase the -semset startup parameter.
If this keeps happening, then you have a potential bug.
In all circumstances, an upgrade to the latest Progress version is advised.
