[Rt-devel] Complex Attachments Cause RT/Apache Hang?

In our RT instance (RT 3.4, modperl, apache 1.3.31, mysql 4.1.13), we 
recently had a problem involving a ticket submitted by e-mail from a 
user; they had attached quite a large number of HTML-formatted e-mails 
to the message to illustrate a problem they were having. Attempting to 
view the body of the RT ticket that resulted from that transaction would 
cause Apache to pin the system's CPU and become unresponsive to other 
requests, and would drag the client's browser to a standstill. 
Restarting Apache solved the problem for both client and server, but it 
could be easily replicated by opening the ticket again.

Is this a known issue for RT? If so, is it resolved in later versions of 
RT, or are there mitigating steps we can take in our current deployment?
