Thanks. Yes, was just doing exactly that. It gets called a lot, and the mutex is wrapped in a class, so I have more control there, to add id's when the class is created, what created it, and a counter to indicate which locks have locked and released.

I'll let you know how that one goes!

Cheers.

Hi David,

Yes, thanks for that. I've checked the spec of the machine and as far as I can tell, it's fine. They're also not running over Citrix or anything like that. I also checked anti-virus. It's possible that it could be an issue, but I can't see anything in it's logs to indicate that it has intervened.

The freeze also does not happen at any particular point during the running of the software, it's a bit random. I've watched it happen with them, and I've checked the resources of the computer when it did happen, and again, they looked fine.

I am also investigating if other software they have running might be interfering. The one thing I know they have running in the background is Worldox DMS. I know they are quite involved bits of software (I'v developed one myself). But I'm not sure how to work out if it has got in the way at all.

Anyway, I'll probably get on another GoTo meet with them and recheck all this. Trouble is when I do, it USUALLY all works fine. Difficult.

Thanks for your input. Good to chat.

Thanks, name is one thing I haven't logged. Will let you know how it goes.

Thanks for your thoughts.

Thanks Kornfeld.

I think I will draw out exactly what threads are being created and where, how long they run for (it looks like 3 thread IDs are being used during the call to the Mutex, so they are in loops througout the duration, if you get my drift).

I will then see if I can spot any obvious way in which one lock may happen and cause another to freeze.

It it your understanding that a mutex lock is only locked on a particular thread?
