Austin,
I was working on this some time back, and I don't believe it's a
Apache problem (it might be a better idea to move it to the PHP mailing
list)
The problem occurs because of the way the PHP context is handled in
php_output_filter (sapi_apache2.c).. Here's something that I observed :
The function php_output_filter() is called > 2 times because of the way the
output data is handled by the filter..
- the first time around some sort of initialization is done.
- during the second round, the data is sent out
- then i don't know what happens (possibly wrong termination of the o/p
brigade), and the php_output_filter is called for the third time.. The
filter knows about such a thing happening, but the code is not written
properly to handle the situation.. The PHP context (ctx) is corrupted, and
the PHP module bombs - you end up seeing only the parent apache process.
(Due to my limited PHP knowledge) I introduced the following snippet just
before the ap_save_brigade(...) block, and it seems to bring up apache
if ((ctx->state < 0) || (ctx->state > 2)) {
ap_log_error(APLOG_MARK, APLOG_DEBUG,
0, NULL, "PHP : Unrecognized state!");
return 0;
}
This is a workaround and not a resolution/fix.. I'd appreciate if anybody
could post a fix for this..
Thanks,
-Madhu

FYI. Not an compilation problem, HTTPD just doesn't do anything, but
doesn't write a log either, and only 1 process is started.
