problem s apachom

[Milan Vician]

Mam problem s Php resp. asi s Apachom, niekedy sa 
stava, ze server vobec neodosle stranku, ked o nu 
prehliadac poziada. Vyzera to tak, ako keby 
webserver v tej chvili ani nebol spusteny.

No a v logoch sa mi objavuje toto:

masina1 kernel log messages:
pid 34586 (httpd), uid 80: exited on signal 11
pid 34585 (httpd), uid 80: exited on signal 11
pid 34584 (httpd), uid 80: exited on signal 11
pid 34583 (httpd), uid 80: exited on signal 11
pid 34582 (httpd), uid 80: exited on signal 11
pid 34581 (httpd), uid 80: exited on signal 11
pid 34580 (httpd), uid 80: exited on signal 11

Neviete mi poradit, co v tomto pripade robit?
