We get many "child pid [xxx] exit signal Segmentation fault (11)" in
out error_log. tracing the pids and shows seg faults on different funtions, most if not all related to php. Thats probably a bug somewhere
on our system, I need help with pin pointing the trouble.
here are the tails of what we found out so far, I hope it will make more sense to someone here then to me.
The following crush happens on many (80% of the segmentation faults) occasion:

The function is:
function draw_menubox_header($titel){
$string = '<table ...>'.
'<td ...>' . $titel .
'...</table>' ;
return($string);
}
?>Those are other type of crushes... All within a time frame of about 15 minutes.
