Collection was modified; enumeration operation may not execute

Describe the Issue

Appears when you start / restart server. Seems to be related be a thread synchronization issue with the message list or foreach loop, can't tell for sure.

Unhandled exception. System.InvalidOperationException: Collection was modified; enumeration operation may not execute.
