we're using mod_php with the php mapscript bindings. initially we had
problems because the binding assume a cgi/transient environment and thought
we'd solved it be relaying the environment. now, however, i'm experiencing
random crashes of the entire httpd server with maplet that looks like this
<?php
#
# relay environment to emulate normal cgi environment
#
reset($_SERVER);
while (list ($key, $val) = each ($_SERVER)) {
putenv("$key=$val");
$_SERVER[$key]=$val;
};
dl("php_mapscript.so");
require('map_equations.php');
$request = ms_newowsrequestobj();
$request->loadparams();
ms_ioinstallstdouttobuffer();
$oMap = ms_newMapobj("./index.map");
$oMap->owsdispatch($request);
$contenttype = ms_iostripstdoutbuffercontenttype();
header("Content-Type: $contenttype");
ms_iogetStdoutBufferBytes();
ms_ioresethandlers();
?>
now, when httpd crashes it crashes big: no error messages or anything and no
response from server whatsoever. considering mod_php is a persistant
environment i'd assume this is memory corruption/lack of resource cleanup.
are there any obivous things i might try to force clean-up and/or
re-initialize the mapscript library on each request? any other suggestions?
btw. running the above cgi via mod_php succeeds only about 70% of the time.
running if from the command-line (forcing weblike environment) works 100% of
the time. i'm in the process of testing normal cgi mode.
regards.

we can deny everything, except that we have the possibility of being better.
simply reflect on that.
