batch add, number of sql connection

[vbussiro]

I got a problem on my gallery www.bussiron.be, batch add only add some files at a time. For example, if I try to add 10 files, only 3 are added, and others have no image for the result of upload. When i click this broken image, result may be ok (which is false) or sql number of connection error.

I think this is the problem here, since my sql database only accept 3 concurrent connections. My provider is OVH.com on a 1000gp plan.

Is there a way to limit number of sql concurrent connection ?

I created a test/test user, but don't have ftp batch add allowed...

thx for any help.
