[rt-users] Ticket creation problem

[Don Beethe]

 Has anyone else seen the following in the rt.log:
DBD::mysql::st execute failed: MySQL server has gone away at
/usr/lib/perl5/site_perl/5.8.5/Apache/Session/Store/DBI.pm line 67,
<DATA> line 225.
(/usr/lib/perl5/site_perl/5.8.5/Apache/Session/Store/DBI.pm:67)

Users are saying they are getting an email for a ticket, but when they
try to click on the link, it says it can't find the ticket. When I look
in the log, I see this. 
Any ideas on what is going on?
