Deadlock is a situation in which two computer programs that share the same resource, prevent each other from accessing the resource. This causes both the programs to cease and neither of the programs is ever executed.

Creo Elements/Direct Drawing Manager and the Java server processes check for deadlocks and stop the affected programs. Creo Elements/Direct Drawing Manager records the deadlock situation in a log file called mm_deadlock_XXXXXX.log (where XXXXX is a randomly-generated number) in the %TEMP% directory.

The Java server processes record the deadlock situation in a log file called <ServiceName>_deadlock.log in the logging directory for the Java Services.
