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

./configure --enable-bcmath --enable-calendar --enable-exif --enable-ftp --enable-gd-native-ttf --enable-libxml --enable-magic-quotes --enable-mbstring --enable-pdo=shared --enable-soap --enable-sockets --enable-wddx --enable-zip --prefix=/usr/local --with-bz2 --with-curl=/opt/curlssl/ --with-curlwrappers --with-freetype-dir=/usr --with-gd --with-gettext --with-imap=/opt/php_with_imap_client/ --with-imap-ssl=/usr --with-jpeg-dir=/usr --with-kerberos --with-libdir=lib64 --with-libexpat-dir=/usr --with-libxml-dir=/opt/xml2 --with-libxml-dir=/opt/xml2/ --with-mcrypt=/opt/libmcrypt/ --with-mhash=/opt/mhash/ --with-mysql=/usr --with-mysql-sock=/var/lib/mysql/mysql.sock --with-openssl=/usr --with-openssl-dir=/usr --with-pdo-mysql=shared --with-pdo-sqlite=shared --with-pic --with-png-dir=/usr --with-pspell --with-sqlite=shared --with-ttf --with-xmlrpc --with-xpm-dir=/usr --with-xsl=/opt/xslt/ --with-zlib --with-zlib-dir=/usr --with-litespeed

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 ??

}
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

thanks

There is a memory limit configuration for lsphp5 external application, login to LSWS web console and check.

eaccelerator memory is counted towards that limit.

[eva2000]

Ah didn't know eccelerator memory is counted too !

is that eaccelerator actual used memory or the max limit defined for eaccelerator that is counted ?

thanks

[mistwang]

eaccelerator always allocate SHM/MMAP memory all at once at beginning.

[eva2000]

eaccelerator was set at 256MB

seems the soft/hard php5 limits in litespeed admin were 400M but I didn't know they were in bytes.. thought it was megabytes, so upped it to 2560 and it worked.

[eva2000]

working with soft/hard limit at 1280 and 2560

seems the soft/hard php5 limits in litespeed admin were 400M but I didn't know they were in bytes.. thought it was megabytes, so upped it to 2560 and it worked.

Like 300M
