can VPS get overloaded?

 

I've been using ForexVPS with copytrade ExpertAdvisor on MT4. So I'm using ForexVPS from ICMarkets on my account with ICMarkets. I'm guessing both: my ForexVPS and ICMarkets platform are running from the same server-room or at least connection between them is excellent.

It was working just fine.

Today, I wanted to copy those trades to my accounts with 3 other Forex brokers. So I installed three additional MT4 on that ForexVPS, added ExpertAdvisor to all of them and now... the copy-trade signals stopped working. Even that first one on ICMarkets didn't execute trades as before.

Have I overloaded my ForexVPS or is this not possible? At first glance, all MT4 + their EAs seem active. Just trades didn't get executed. ForexVPS's pricing page says I can launch up to 3-4 MT4s on one VPS.
