Symptoms

Caution:   This note is based purely on Microsoft documentation.   It involves making modifications to the registry which can have serious, negative impacts on your installation if done incorrectly. Microsoft recommends having a backup of your registry and/or system before making registry changes.


This problem is specific to MS Windows Operating Systems - normally Windows 2000 or 2003 or 2008, 2012 but can happen on any windows version.  Although the occurrence of this issue is not common, it appears on both 32 and 64 bit windows.  Note that on 64 bits windows using 64 bit 11g or 12c Forms the problem threshold may be around 170.    You may receive the following error indications:

Forms 11g - FRM-93552
Forms 6i, 9.0.4.X, 10.1.2.X - FRM-92050 sometimes together with FRM-92101 or FRM-92102
Forms 9.0.4.X, 10.1.2.X - application.log shows FRM-93000
Forms 6i (Forms Listener Servlet) - jserv.log shows FRM-93000
Forms 6i (Forms Server) - error log shows ERROR 1444 - FORMS SERVICE STOPS UNEXPECTEDLY 1444

This happens with a small number of connections - the range may be 50 - 80 on 32 bit and around 170 on 64 bit machines. The specific number depends on operating system factors such as number of CPUs, processor speed, memory, etc.   The problem may occur even with less than 50.
