Two problems are existing in current Dollar Universe versions regading file watchers:
1. File Watchers leaves an event in status 'started' which never gets removed automatically.
Even if the triggered Uproc has the option 'No Memorization'.
2. If a file watchers is executed that runs a uproc that belongs to a compatibility class, a class event will created that never will be purged.
This happens when the first condition match takes place, the event status is 'opened' will remain indefinitely.
Dollar Universe : 6.x and 7.x
These are defects in the Dollar Universe solution that can be encountered when file watchers are used.
In current version, refrain from using uproc conditioned on uprocs classes
A fix to these problems will come in a coming version of the Dollar Universe Solution.
