summary: Yet another MUC reliability module
rockspec:
  dependencies:
  - mod_track_muc_joins
labels:
- Stage-Alpha
...


This module reacts to [server-to-server][doc:s2s] connections closing by
performing [XEP-0410: MUC Self-Ping] from the server side to check if
users are still connected to MUCs they have joined according
[mod_track_muc_joins].  If it can't be confirmed that the user is still
joined then their client devices are notified about this allowing them
to re-join.
