mysql_connect or mysql_pconnect or DEATH ???

I have a chat software working on www.jumatateata.ro The problem is that all the time I get mysql sessions opened and I don't understand. I used mysql_connect (at the beggining of every script) and mysql_close in the end. The ISP told me that still remain mysql sessions opened. Then I used mysql_pconnect and again, too many sessions opened. What makes everything hard is that I don't have telnet acces so this is my next question: How I can see mysql sessions opened just using a php script ? Can I ? (I'm asking this because I was thinking that I can write a php script to show me the sessions.=) Do you have any idea about this ? I'm really interested to find out... Thanx a lot...
