apache usage excessive - by lyron

[saturnus]

Hi, one of my accounts(i am a reseller) Has been suspended because of this reason "apache usage excessive - by lyron".
This accounts uses only a topsites script,Topsites scripts are very common nowdays,Also doesn't use Any email feature,So it cannot be blamed for spam,
Offcourse a TOPSITES SCRIPT with 150 websites members use about 5GIGS/months.
My question is: What is the LIMIT for apache usage? If there is a limit i think we must know it.So we can arrange for an extra payment in this case.
Also i want to ask this question:
We pay every month for 50 gigs monthly transfer.We can use them or not?
Or every time one of our websites uses 3-4 gigs/month it will be suspended for "apache usage excessive" reasons?
We are willing to pay more if this is the problem,but we need reliable hosting services.
Please if anyone has a personal opinion on the policy of hostgator on this subject let me know..

The only time we suspend a site for something such as that is if it is getting so many requests that it is crashing Apache and making the server unusable.
