[rt-users] Ticket Duplication

[Testwreq Wreq]

We are using Rt 4.0.8 with mysql and sendmail

Our RT tickets are created by our users by sending an email to rt at ....

Randomly some of the tickets are duplicating on creation. So far I am
unable to find any pattern in this duplication.

Can some one please guide how to troubleshoot this issue. Which logs should
I be looking at?

Thanks much! I will appreciate all the responses.
