Hmmm I'm not sure, but you might be one to something. I usually don't wait 
very long and did multiple "-loader reset", but it might still be too long .

But I did some tests, use case :
1- Stop -loader
2- Start -loader
3- Add member to group

If I do 2 and 3 fast enough (less than 30 secs), the change will usually 
work. Since the cron is programmed to be every minute, if I do another change 
between the success and the other execution, it will fail. So I might have a 
1 minute timeout. I'm not sure where this would be happening.

Could it be a firewall issue that would drop the connection ?
Could you make it so that a new root session is created each time ?

PS.
Found this in my logs when starting the -loader, I'm not sure if it's normal 
, but it might be related :
2012-02-23 14:41:00,085: [DefaultQuartzScheduler_Worker-2] INFO  
Psp.getPSP(172) -  - Loading psp from configuration directory 'null'

Do you think it is a timeout issue ? In other words, does the "null session 
member" exception get thrown right away, or after awhile ? If awhile, is that 
minutes, hours, or ?
