Check_MK Werk 8552: Notification spooling: Fixed "Corrupted spoolfile" in case spool files are created

ID: 8552 Title: Notification spooling: Fixed "Corrupted spoolfile" in case spool files are created Component: Notifications Level: 1 Class: Bug fix Version: 1.4.0i1 Fixed a race condition between the producing side (the notification module which creates the spool file) and the consuming side (the mknotifyd which processes the spool files) that made the mknotifyd process incompletely written files. This could cause "corrupted spoolfile" error messages in the var/log/mknotifyd.log and resulted in spool files being moved to the directory var/check_mk/notify/corrupted. The notifications are not sent out in this situation.
