Unhandled Exception: Collection was modified; enumeration operation may not execute.

The last several weeks I have been experiencing server crashes with the error below.  I am using pathsubstitution and have real time monitoring set to Auto.

I usually dont post unless I have a problem but until now I have enjoyed stable releases for many months, great work keeping the issues down.

 

 

Version 3.1.16.0

 

*UPDATE** SERVER LOG:

Not sure, but this seems to happen when the server has downloaded an update and waiting for a reboot. Could it be that setting to Auto is changing a collection while it is being enumerated? 

 

*Update: Turned OFF real time monitoring and there were no updates last night and still got 3x of the errors.  Two (2) at 11pm and one (1) at 3am that crashed the server.
