Affects pre-release 4.8.0 only.

When:

• CSI is enabled and configured to delay unimportant stanzas

• a client supports it

• a client goes inactive

• activity occurs that queues a list opf stanzas for the client

Then:

• the client misses stanzas

• MUC membership appears to drift over time

Investigation showed that stanzas weren’t being delivered whilst Inactive, but that the queue was being emptied. Investigation also showed that disabling the delay resolved the problem.

Could this be the problem?

Is this only flushing one queued stanza when the client becomes Active?
