Open Diameter

Hi,

I am using Open diameter i version and make it work as a diameter client. As a client, it will send CER to diameter server firstly and wait for the CEA from server. If server didn't give any response, client will trigger connection retry.
Then problem appears. About 2MB block is lost each time open diameter does connection retry. After a long time, retry doesn't work and errno=24--Too many open files will be reported in log.

Does anybody meet such a problem? How to solve it? Thanks!!
