Restarting the providers using the already implemented SIGUSR2 (for
|
||
|
|
method .resetOffline, used after netlink detects an interface change)
|
||
|
|
when a time drift is detected, ensures that affected connection retries
|
||
|
|
(e.g. LDAP) will be rescheduled immediately instead of having to wait
|
||
|
|
the time shifted to return to its normal execution.
