litespeed PHP memory_limit not being recognised ??

[eva2000]

Hi

I seem to be stumped on a PHP memory_limit exceeded message of which the usual php.ini edits have no use.

I've edited

/usr/local/lib/php.ini
/usr/local/lsws/php/php.ini

Both to memory_limit = 256 and restarted lightspeed but still stuck around max 32-37MB for php ? Is this because php was compiled without memory-limit flag ?

PHPINFO reports 256M memory_limit

memory_limit	256M	256M

configure command

but using test script as well as in drupal 5.19 and vbdrupal 5.19 scripts I am hitting memory_limit at around 32-37MB ??

phpmemory.php script contents

<?php
// phpmemory.php

$memlimit = 256;
print 'Expected memory limit ' . $memlimit . 'MB <br />';

$memory_mb = round(memory_get_usage() /1024/1024 , 2);

$pattern = str_repeat("0123456789", 1000);
$fill = str_repeat($pattern, 1);
$counter = 1000;
while ( $counter <= 27000 ) {
    unset($fill);
    $memory_mb = round(memory_get_usage() /1024/1024 , 2);
    print 'Clear -> ' . memory_get_usage() . ' (' . $memory_mb . ' MB) <br />';

    print $counter . ' x 10000 chars -> ' ;
    $fill = str_repeat($pattern, $counter);
    $memory_mb = round(memory_get_usage() /1024/1024 , 2);
    print  memory_get_usage() . ' (' . $memory_mb . ' MB)'. ' [' . $memory_pct = round($memory_mb /
$memlimit *100 , 1) . ' percent]<br />';
    $counter = $counter + 500;
}
print '<br />If you can see this, the server can allocate something close to 256mb';
?>

So is there are php memory limit in litespeed elsewhere that needs editing ? I tried copying php.ini over to /home/username as well and that didn't work either ?

If php needs to be recompiled with memory limit flag, where do I recompile it from litespeed admin for web1 and web2 servers or from WHM easyapache ?

Rest of details:

On WHM/Cpanel 11.25.xx based server with litespeed 4.0.12 on 2x web servers load balanced using haproxy where load balancer ip is xxx.xx.xxx.x13

Both web1 and web2 have:

• PHP 5.2.12 + Eaccelerator
• Memcached 1.2.8 and Memache 2.2.5 installed
