[Glass] GemTools backup error

[James Foster]

It looks like the backup failed because the GC Lock was not available. When that happens what do you get from the following:
	System sessionIdHoldingGcLock.
	System voteStateString.
Repository-wide garbage collection is a complex area. Have you watched any of the architecture videos at https://programminggems.wordpress.com/2010/02/05/scaling-objects-videos/, especially #20 and #22 on garbage collection?

Do you have logged-in sessions that are idle and not committing? This would hold up voting.

If you stop all the sessions without restarting the stone and try again a few minutes later does it work?
