Target list - stop importation after about 1000 entries

Hi,

I have three servers running differents instances of SuiteCrm, on each of them I have trouble importing accounts, contacts and other objects.
It starts normally but after many seconds ( like 20-30 seconds ) the popup vanish and regardless how many accounts I selected, it only import about 1000 entries, when I try again it add like 5 entries to my list but I can’t import more.

It’s the same on the three servers.

Have you already seen this kind of troubles ? Do you have any solutions ?

Thanks for your help

check you php.ini for time and upload limits

best regards
