Minimserver java exception error

Woke up this morning and minimserver appeared offline and there was an exception error in the log. The detail is below:

Control point - Lumin on ipad Air all up to date versions (typically use Kazoo but was just trying it this morning for the first time in ages and so it would have probably needed to resync it's database etc. but it seemed to show as offline immediately).

Melco N1A - minimserver 75 updated yesterday (along with minimwatch)

The NAS and file system were all visible and accessible using windows explorer but minimwatch showed the Melco in red.

I simply restarted and things seem to be OK now. - but thought I should post the detail here for record.

Thanks for letting me know about this. I can imagine a very unusual combination of circumstances that might possibly produce this stack trace. I have added some code that I hope will prevent this or make it much less likely to occur.

Thanks Simon. I haven't seen it since and everything has been working well.

I have found out what was causing this and it is now fixed in MinimServer update 76. Thanks very much for letting me know about the problem.
