MySQL: table "sessions" in which there is a field "a_session" which type is 
appropriated "longblob". At testing for the big size of a DB (~1.5Gb) and 
quantity tickets (~50000), brakes begin. Ticket opens about one minute (a lot 
of tickets number is raises), perl eats all system resources, references to 
DB do not occur (strace -p PID on a demon httpd at work apache with 
mod_perl - gives out: time (NULL) = 1201000846). It has been noticed only 
casual by image if to expose type "a_session" in "longtext" (that is not 
correct type) all starts to work it is remarkable, only, naturally, sessions 
cease to work.
Set ($WebSessionClass, ' Apache:: Session:: File '); which is responsible for 
storage of sessions not in a DB - as any successes has not given. Sessions 
work, RT hangs. PostgreSQL: a similar situation.

Gentoo 2007.0
MySQL 5.0.44 or PostgreSQL 8.2.6
Perl 5.8.8
apache 2.2.6 with mod_perl or nginx with fastcgi 0.6.25
