Hi Dave!

We have the same configuration for all nodes. The cleaner is scheduled to run 
20 seconds after the application starts and then periodically once per hour 
(the original value is greater than that: 5000 s).

Because we don’t start the nodes at the same time, the cleaner also runs at 
different time on different nodes. We don’t do any locking or anything like 
that. I think that the cleaner simply removes some tickets locally and then the 
deletions get replicated to other nodes, so they are in fact deleted on those 
other nodes too. But I don’t know the implementation, so I may be wrong on this.

We introduced the cleaner quite recently, so unfortunately I have very little 
real experience it. Should I found something more concerning the cleaner, I 
will post it to this list.

Best Regards,
   Jarda

Hi Jaroslav,

Well, given the error I knew it had to be something like that - I just couldn't 
find where logoutManager was supposed to be defined.  Thanks for pointing me in 
the correct direction. :-)

A couple last questions on your setup:

Are you running the ticket cleaner on multiple nodes of your environment 
simultaneously, or just one?  If you run multiple simultaneous cleaners are you 
doing any kind of locking on the cache to prevent them from stepping on each 
other, or has it never been a problem for you?

Thanks,
Dave
