Description Baldur 2013-08-15 11:58:38 UTC
Start Debugging an iOS project on a available build machine. iOS simulator opens on the MAC and the program runs. Activity monitor shows an MtbServer process running on the mac. After less than a minute i get from the Mac Server Log:

[2013-08-15 15:49:22.5] Command [DebugApplication: CommmandUrl=DebugApplication] finished (13)
[2013-08-15 15:49:22.5] Handling with command: [ChangeActiveApplication: CommmandUrl=ChangeActiveApplication] (11)
[2013-08-15 15:49:22.5] Attempting to acquire command execution lock, timeout set to 00:10:00
[2013-08-15 15:49:22.5] Command [ChangeActiveApplication: CommmandUrl=ChangeActiveApplication] finished (11)
[2013-08-15 15:50:17.6] mtbserver: No KEEPALIVE command, exiting...

Now no mtbserver process is showing in Activity Monitor. 

I refresh the connection and get:
[2013-08-15 15:52:15.5] ERROR: Another instance is running
[2013-08-15 15:52:16.0] ERROR: Another instance is running

and one mtbserver process arrives on the MAC Activity Monitor and i am unable to Debug again.

The mtbserver exited making it incredibly time consuming to Work with VS and iOS

To make a connection to the build machine and hold onto it until i close it.

Hi Baldur,
  We are aware of this issue. As a temporary work around could you try
going to Tools-> Options -> Xamarin -> iOS -> Configure and selecting the host again, which shuold then re-establish a connection to the build machine. This should hopefully be slightly less hassle, while we fix it.

I believe a fix for this has been implemented, as I am unable to reproduce this issue. This fix should be included when we release 1.6.x -- ideally by the end of the month.
