48573 Linux/Interchange server help

We have a dedicated server running Fedora and ICDevGroup's Interchange. Last two days we have been experiencing issues with interchange (after restart the Interchange server immediatley stops. restart says it terminated with an error). yesterday we were able to get it restarted after discovering one of the catalog [login to view URL] files was over 2GB and removing it. Today we are having same error but error log size is not the issue. Wish to contract programmer to assist in debugging Interchange issue. (fyi, this server has been running for 2 years with no issuse, rebuilt last month and running fine for the month. It is not an install issue). Feel free to quote for full debug job or hourly. My feedback profile insures promt payment in any method you wish to work in. Thanks.
