Subject: [PATCH 7/8] core: move start ratelimiting check after condition
|
|
checks
|
|
|
|
With #2564 unit start rate limiting was moved from after the condition checks
|
|
are to before they are made, in an attempt to fix #2467. This however resulted
|
|
in #2684. However, with a previous commit a concept of per socket unit trigger
|
|
rate limiting has been added, to fix #2467 more comprehensively, hence the
|
|
start limit can be moved after the condition checks again, thus fixing #2684.
|
|
|
|
Fixes: #2684
|
|
(cherry picked from commit 7629ec4642b03517742d09b7303c204fddf82108)
|
|
Resolves: #1350686
