Hi - glad you are finding it useful.

What you describe is certainly not normal behaviour. Could be caused by a number of things - hopefully not a bug, but if it is I will have to look into it.

How long is your server monitor cycle? It defaults to 30 seconds. If you have entered a larger number then the maintenance may wait until the next cycle before attempting to start the server again.

I take it that starting the server manually via GSM works ok? If it does then that eliminates a config issue there.

If you have a lengthy shutdown delay time, then that may also cause a hang for that length of time. This is there so that the server can perform any saves before GSM does other things. Slower machines generally require longer delays.

If you click "Perform maintenance", does it work correctly that way?
