Mutex: ZoneServer::MMasterSpawnLock

[John Adams]

My dev server tolerated me, Jabantiz and Xinux, zoning all over the new zones repeatedly, talking 1/2 the night away, killing ourselves and our foe... and at 6am I decide to /exit, and the zone throws an exception. Seriously?

Getting the feeling this is not really a valid exception, but a mis-placed IF or something... Jab?

It looks like the spawn loop in the zone deadlocked when the zone was trying to shut down, no clue why it would have happened after we screwed around so long on it last night. Judging by the times for Initiating zone shutdown and zone shutdown complete I would say it is very likely the zone deadlocked but did recover. Will just have to keep an eye out for this again and see if we can find a way to reproduce it.

Pretty sure I see this mostly when it is a non-clean logoff. crash or exit.

Jab, not sure if this helps, but I might have found a quick way to reproduce this issue. I am on my local world with my minilogin having the opcodes for 1194 client, yet my world does not (still only has 1096 max). Created a character and habitually clicked Play and of course, get bounced because of the version incompatibility.

What I didn't expect was to see Frostfang deadlock right away. Zero spawns in zone, except for my player, which should not have even gotten into the zone due to the version incompatibility.
