Synchronization of groups doesnt work in specified schedule(* * * * *) but is pretty random

[jsemfila]

We do use this definition of CR with synchronization every minute, but synchronization appears to happen once in an hour randomly. We did go throught logs and almost all related resources, but did not find anything related to this issue.
