[users@httpd] error when using httpd-2.2 with cgi and fcgi

["Alex Joseph" <cax0cn@xxxxxxxxx>]

HI, list:
      I'm using httpd-2.2.2 with mod_cgid and mod_fastcgi-2.4.2 under RHEL-as4u3 with the default kernel, the compiling parameters are listed below:
$ bin/httpd -l
Compiled in modules:
  core.c
  mod_log_config.c
  event.c
  http_core.c
  mod_mime.c
  mod_cgid.c
  mod_dir.c
  mod_alias.c
  mod_so.c

there  are always so many errors that I got a very high loadaverage, they are of three types:
1, sometimes there are several *defunct* cgi and one or two *defunct* fcgi.
2, after graceful, there will be many fcgis and cgis, most of them will quit by themself; after killing, they sometimes will emerg again, with no operation except high volume visiting.
3, some cgis run much longger, and most of these will become orphan which cost much cpu time resulting a terribly high load.

I've checked on the net, but cannot find anything helpful.
Is there some directions avaliable?
thanks for any notice.

sincerecely alex.
