%Internal error: enter_kernel: deadlock
    

	Hello,

	DECmcc T1.2.7 with VMS V5-4.1

	I've got the same error "... enter_kernel: deadlock" during the
	registration of an entity instance from the iconic map; the
        registration has been done successfully but DECmcc exits.

	Here is the messages I've got :	
    
SEGUR::Trompette � mcc_dcw
%MCC-S-NORMAL, normal successful completion
%MCC-S-NORMAL, normal successful completion
%Internal error: terminate_thread: continued after termination
%CMA-F-BUGCHECK, internal error detected in DECthreads
%Internal error: thread_base: exception during thread termination
%Internal error: enter_kernel: deadlock
%CMA-F-BUGCHECK, internal error detected in DECthreads

This error message is generated by CMA/DECthreads (BL 9 and 10)
which it detects that is trying to schedule a terminated
thread to run on a virtual processor.  We are still working with
the CMA developers - trying to track this problem down.  Current
thought is that the Thread-ready-queue is corrupted by ????

The problem occurs both on VMS and ULTRIX.
