You should configure enough database Work-in-Progress (WIP) connections to accommodate potential runtime-driven work-load.
To do so, add the following property to the [Event_Management] section of the InterchangeSystem.cfg file:
MIN_CONNECTIONS = n
Where
n=sum_of_all_max_threads_for_collabs_used_simultaneously_plus_num _connectors
The sum_of_all_max_threads_for_collabs_used_simultaneously is the sum of the Maximum number of concurrent events settings of all the collaboration objects.
Setting a sufficient minimum number of WIP connections helps eliminate the possibility of a server crash in circumstances where the server is attempting to reboot, and all connectors are trying to do WIP work while all collaboration threads are undergoing wip-commit.
