getting tons of 503 errors

[bhanuprasad1981]

customers are complaining lot of 503 errors , thought upgrading cpu lisense will get rid of it , but no still errors continues, i checked logs and found lot of these type of errors :-

another type error in logs :-

[70.37.60.245:49608-0#APVH_site.net] POST request in process stage, fail with 503

this is likely a PHP code problem that crashes LSPHP process. you may want to check stderr.log and/or run the php script from command line to narrow down the code issue.

please increase lsphp5 (external app) process limit.

its not for one site but many sites all are vbulletin sites, any how as per you other reply i have increased process limit a bit
before soft 200 now 300
before hard 300 now 400

hope it works

also i am failing to install / activate xcache on server, installing xcache regular way way is not working , if i try compile php using litespeed admin option , i am missing too many modules like ionciube, mysql etc please help , i cant even pm you .

[webizen]

if install xcache from source (http://xcache.lighttpd.net/wiki/InstallFromSource) and build shared module (.so file), you need to specify correct path to phpize (for lsphp5, it is usually /usr/local/lsws/lsphp5/bin/phpize). to activate, run

cat xcache.ini >> /path/to/php.ini (e.g. /usr/local/lsws/lsphp5/lib/php/php.ini)
service lsws restart

if compile php with lsws admin cp, you need to '--with-mysql' compilation option for mysql.

for ioncube module, just download from http://www.ioncube.com/loaders.php and add entry in php.ini

zend_extension="/path/to/ioncube_loader_lin_x.x.so"

i see in phpinfo, these are php configure when i use match php option :-

'./configure' '--enable-bcmath' '--enable-calendar' '--enable-ftp' '--enable-libxml' '--enable-mbstring' '--enable-pdo=shared' '--enable-sockets' '--prefix=/usr/local' '--with-curl=/opt/curlssl/' '--with-gd' '--with-imap=/opt/php_with_imap_client/' '--with-imap-ssl=/usr' '--with-jpeg-dir=/usr' '--with-kerberos' '--with-libdir=lib64' '--with-libxml-dir=/opt/xml2/' '--with-mcrypt=/opt/libmcrypt/' '--with-mysql=/usr' '--with-mysql-sock=/var/lib/mysql/mysql.sock' '--with-mysqli=/usr/bin/mysql_config' '--with-openssl=/usr' '--with-openssl-dir=/usr' '--with-pcre-regex=/opt/pcre' '--with-pdo-mysql=shared' '--with-pdo-sqlite=shared' '--with-pic' '--with-png-dir=/usr' '--with-sqlite=shared' '--with-xpm-dir=/usr' '--with-zlib' '--with-zlib-dir=/usr' '--with-litespeed'

when i try to compile directly using litespeed i only see these :-

--with-mysqli --with-zlib --with-gd --enable-shmop --enable-track-vars --enable-sockets --enable-sysvsem --enable-sysvshm --enable-magic-quotes --enable-mbstring --with-iconv

when i try to compile directly using litespeed i only see these :-

those are default options, change them to match php option, and check XCache option. so you can build matching php at lsws admin console.

[bhanuprasad1981]

can i use this command

--with-mysql=/usr --with-mysql-sock=/var/lib/mysql/mysql.sock  --with-mysqli --with-zlib --with-gd --enable-shmop --enable-track-vars --enable-sockets --enable-sysvsem --enable-sysvshm --enable-magic-quotes --enable-mbstring --with-iconv --enable-bcmath --enable-calendar --enable-ftp --enable-libxml --enable-pdo=shared --with-curl=/opt/curlssl/ --with-imap=/opt/php_with_imap_client/ --with-imap-ssl=/usr --with-jpeg-dir=/usr --with-kerberos --with-libdir=lib64 --with-libxml-dir=/opt/xml2/ --with-mcrypt=/opt/libmcrypt/ --with-openssl=/usr --with-openssl-dir=/usr --with-pcre-regex=/opt/pcre --with-pdo-mysql=shared --with-pdo-sqlite=shared --with-pic --with-png-dir=/usr --with-sqlite=shared --with-xpm-dir=/usr --with-zlib --with-zlib-dir=/usr --with-litespeed

[NiteWave]

looks ok.
maybe use original
--with-mysqli=/usr/bin/mysql_config
than
--with-mysqli

is better or either is ok.
