Out of Threads
A Callobject can crash if it consumes an excessive number of threads. Usually this limit is twice the number of threadpoolsize as set in jde.ini. This will also produce a .dmp.log file which will contain a list of all threads and their callstacks - this will help in determining where the source of the threads. On System-i enterprise server, there will not be any dmp file. Instead the callstacks for all threads will be logged in jde.log.
