httpd process never die

I have a server where since 48 hours ago http process never die. I have to restart the apache server every few minutes

here is an example of top:

18:26:47 up 55 min, 1 user, load average: 4.81, 4.62, 8.74
182 processes: 171 sleeping, 7 running, 4 zombie, 0 stopped
CPU states: cpu user nice system irq softirq iowait idle
total 98.0% 0.0% 1.5% 0.3% 0.0% 0.0% 0.0%
Mem: 1026976k av, 905492k used, 121484k free, 0k shrd, 159700k buff

Swap: 2040212k av, 61872k used, 1978340k free 436964k cached

PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND
16095 nobody 25 0 16228 15M 3688 R 31.6 1.5 1:05 0 httpd
16075 nobody 25 0 16620 16M 3636 R 31.2 1.6 1:05 0 httpd
16452 nobody 25 0 15372 15M 3660 R 29.6 1.4 0:32 0 httpd


this three process are eating all cpu process and never expire

Any idea?
