I was told this was a PHP problem, and to submit a bug report. I'm not
too sure what such a bug report would look like, or even if this is a

Below is the message I sent to an Apache list, could someone tell me
whether my problem is crummy code, or an actual problem with
PHP/Apache?
Thanks

Subject: PHP Script causing recursive free() calls (?)
I've got quite a problem with part of a PHP script I wrote causing
Apache too fill up it's error logs with:
httpd in free(): warning: chunk is already free.
httpd in free(): warning: chunk is already free.
httpd in malloc(): warning: recursive call.
FATAL: emalloc(): Unable to allocate 256 bytes
Each call of this script will put about 20 megs in my error log.
My Apache setup is:
Apache/1.3.20 (Unix)
mod_ssl/2.8.4
OpenSSL/0.9.6b
PHP/4.0.6
And my phpinfo page is at chris.upnix.com/index.php
The part of my PHP script that's causing the problem (sorry about the
wraping):
/* If no errors, submit junk to database */
if(!isset($Error)) {
for($i = 1; $i = $Days; $i++) {
/* Write to bookings first */
$QueryString = INSERT INTO bookings VALUES(nextval('BID'),
'$CompanyID', ' . $TimeSpan[$i] . ', '$TimeF', '$TimeT',
'$PricePerUnit');
$Query = pg_exec($Connect, $QueryString);
$OID = pg_getlastoid($Query);
/* Find the BID we were given */
$QueryString = SELECT bid FROM bookings WHERE oid = ' . $OID . ';
$Query = pg_exec($Connect, $QueryString);
$Result = pg_fetch_array($Query, 0);
$BID = $Result['bid'];
/* Go through our therapists */
foreach($Therapists[$i] as $Key = $TherapistID) {
$QueryString = INSERT INTO bookedtherapist VALUES(' . $BID .
',
'$TherapistID', '$TimeF', '$TimeT');
pg_exec($Connect, $QueryString);
}
}
/* Everything Should be done, send us off to schview.php */
header(Location: . $BaseURL . admin/schview.php);
exit;
}
I've tried rewriting little parts of this script, but haven't had any
luck in stopping the errors. Also, I've recompiled everything twice
now, which also didn't help. Any help would be appreciated.
Thanks,
Chris
This comes from someone who has no experience with Postgres, but I
suspect that you may be getting into trouble inside your for and foreach
loops where you do apossibly huge number of inserts without freeing used
result pointers. Try doing a pg_free_result after each insert and see if
that helps.
