Comment 0 for bug 1891117

The rsync connection limit is intended to preserve I/O bandwidth.

Depending on the configuration of the mirror, it may be handling multiple roles with separate and essentially independent I/O subsystems.

In this case it might be useful to tune the rsync limits per role.

This can be done by setting "lock file" to a different value in the module config.

See also LP:1891103 for another bug that may have implications for this.
