	We have two clusters, with major manufacturing importance,
	which run fairly extensive scheduler processing every evening.

	In order to monitor (and troubleshoot) this processing, our
	operations staff have an scheduler x-windows display running
	which showws them the nightly flow and any potential problems.
	This window is displayed on a DECstation 3100.

	We have run this configuration for years with no problems until
	now.

	One of our clusters has been upgraded to OpenVMS 6.1 and since then,
	the SCHEDULER$XUI process hangs in LEF state, stuck in the
	SYS$SCHED service routine. This is the same problem described
	in an earlier  reply to this note.

	The last statement (feb/94) stated that there was no fix until
	version 3.0 of Scheduler.

	That was two years ago and we need a solution now. Can anyone
	shed any light on this?

	Charlie
