I dunno whether it's the php memory management's problem, the phplib's problem, or my
coding's problem. Apparently, I'm facing a memory leak's problem that has no solution
at all until now. Please help if someone faced the same situation before.
When I run follow script using OCI8 function, this script use a lot of system memory. when a large
number of user access this script, the httpd is running extremely wierd exactly heap size. The
memory usage is kept on increasing without stopping.
Environment : Oracle8.1.5
script :
<?php
$conn = OCILogon("scott","tiger");
if(!$conn) {
echo "ocilogon1 errornn";
exit;
}
$query = "select userno from chkuser ";
$query .= " where kname = 'test' ";
$stmt = OCIParse($conn,$query);
OCIExecute($stmt);
OCIFetchInto($stmt,$CHKUSER,OCI_ASSOC);
$usernum = $CHKUSER["USERNO"];
OCIFreeStatement($stmt);
OCILogoff($conn);
echo $usernum." --test break1 n";
?>
command for checking memory :
pmap -x 26749(pid)
other command for checking memory :
ps -ef -o pid -o vsz -o rss -o fname -o args | grep httpd | sort
before running above script :
26749 10704 4168 libhttpd /H2K/HiTEL2000/webservice/apache/bin/httpd
26752 10704 1808 libhttpd /H2K/HiTEL2000/webservice/apache/bin/httpd
26753 10704 1784 libhttpd /H2K/HiTEL2000/webservice/apache/bin/httpd

26756 10704 1784 libhttpd /H2K/HiTEL2000/webservice/apache/bin/httpd
after running above script :
