Description

When several cluster-wide sessions are active and one of them is deactivated, sessiond seems to hang.
This causes a timeout in our application (TraceP), which happens 70 seconds after the call to lttng to stop the session.
The scenario is as follows:
- 4-node cluster each with a sessiond/consumerd pair
- 4 test apps running before the sessions are created. They are never stopped
- 4 cluster-wide sessions are created with several events and allowed to run for 10 sec.
- The sessions are stopped one after the other.

A log was collected with verbose mode on one of the nodes (SC-1). The issue takes place in several of the nodes, but it is seen for the 1st time on node SC-1 at the enf of the log (the rest of the log was omitted since it was a bit large)
