I have seen this type of problem after a reboot in the following circumstances (granted, it was Solaris, but the principle is the same):
1. Server is booted
2. A new filesystem is mounted, but not updated in vfstab
3. A utility to do some task (like cleanup) is called from the new filesystem
4. Server is rebooted
5. The filesystem is not mounted at boot time
6. The utility is called to perform the cleanup task - but there's nothing there.
7. The application crashes quietly, you end up with defunct processes.

NAME

       filesystem - event signalling that filesystems have been mounted

SYNOPSIS

       filesystem [ENV]...

DESCRIPTION

       The  filesystem	event  is  generated by the mountall(8) daemon after it has mounted all filesystems listed in fstab(5).  mountall(8) emits
       this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with other activity.

EXAMPLE

       A service that wishes to be running once filesystems are mounted might use:

	      start on filesystem
