[Pkg-nagios-devel] Bug#725826: nagios3: re-schedule a next service check leads to multiple checks in the normal check period

[Marc Leurent]

UPDATE: I think I was thinking that problem was solved in nagios 3.5.1 (and Vaclav too based on experience on Fedora with nagios 3.5.1) because it is more difficult to reproduce and problem occurs less often


* Next Steps
1) Can some other people reproduce / acknowledge the problem
2) Test version 4.x


* Steps To Reproduce
1) Do several reschedule of the check
2) Reload nagios
3) Do several reschedule of the check


### Logs of my check on nagios 3.4.1-5
=> Using the "Steps To Reproduce", I can have the check duplicated many many times
