external mysql connect error

i run a filehosting site for which i bought a new extra downloadserver. to host files on this external server this it needs to make a connection to mainserver's mysql. the mainserver is often at 100% of its bandwidth which seems to cause that the external mysql connection fails. when mainserver is at 100% of its bandwidth the pings also become higher, but new extra server is located at same provider so pings can't be that high between servers. me and my coder tried many things but we can't explain why this isn't working, all mysql settings seem to be ok. hopefully someone here knows a solution or thinks he can fix this for me. error we get: **Warning**: mysql_connect(): Lost connection to MySQL server during query in **/home/yourfileserver/public_html/[login to view URL]** on line **6 ** ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
