Apache processes get increased dramatically

Hi,

I would like to confirm with you about the following behavior:

EBS:12.1.3
After we logged into EBS, then we use tab key to focus on the button such as [Personalize] or [Full List] then keep pushing the enter key for a while(like 10, 20 seconds)
The httpd processes get increased dramatically..

Example)
dlebshub2@src121@APPS> ps -ef|grep src121|grep -v grep|grep httpd| wc -l
12

--keep pushing the enter key--

dlebshub2@src121@APPS> ps -ef|grep src121|grep -v grep|grep httpd| wc -l
228


We are worrying if some users unconsciously done this, then the number of process  exceed the number of MaxClient.
