[rt-users] upgraded to 3.8.2 now getting "MySQL server has gone away error"

[Alan.Lu at interactivedata.com]

I've just upgraded RT from 3.6.1 on a RHEL4 i386 to 3.8.2 on a RHEL5 
x86_64.
I followed instructions in README and UPGRADE.mysql and there was no 
errors during the procedure.

Now the problem is: when I create a new ticket in a queue, and if there 
are more than one user in AdminCc, then I'll get "MySQL server has gone 
away error"  in rt log as detailed below. If I just update a ticket no 
problems. If the queue only has one user in AdminCc, no problems.

Any ideas?
