[Solved] Default PHP page: fork() failed, please increase process limit

I've read quite a lot of posts related to this, but none seem to solve my issues

When I visit my default PHP page (http://localhost:8090/phpinfo.php), I get the following:
503 Service Unavailable
The server is temporarily busy, try again later! Powered By LiteSpeed Web Server

(The "hello world" cgi page is fine)

This is a new install of litespeed (1st time I have used it)
The version is: v4.2.2
I'm using it on a Ubuntu Virtial server (VM ware). I've recently updated + upgraded (sudo apt-get update && sudo apt-get upgrade) to make sure all the packages are the latest

I've given the VMware 4 processors and 8 gigs

I've managed to install the PHP (eventually) without errors via the litespeed confMgr
I did have to do a few things here to begin with, but they were resolved using the info here:
http://www.litespeedtech.com/support/wiki/doku.php?id=litespeed_wiki:php:lsapi:troubleshoot

The error messages suggest increasing the soft/hard process limit, so I've updated these via the confMgr (Configuration >> Server >> Security)
1) soft (from about 300) now to 1300
2) hard (from about 600) now to 1600

I've also tried setting both of these to 0 (the machine default), but I still get the error messages below when visiting the default php page:


There error in the stderr.log is:
2013-02-25 05:52:02.837 [STDERR] fork() failed, please increase process limit: Resource temporarily unavailable

The error in error.log is:

That returns the following:


phpinfo()
PHP Version => 5.4.11

System => Linux ubuntu 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:32:08 UTC 2012 i686
Build Date => Feb 25 2013 08:52:37
Configure Command => './configure' '--prefix=/home/mike/lsws/lsphp5' '--with-mysqli' '--with-zlib' '--with-gd' '--enable-shmop' '--enable-track-vars' '--enable-sockets' '--enable-sysvsem' '--enable-sysvshm' '--enable-magic-quotes' '--enable-mbstring' '--with-iconv' '--with-litespeed'
Server API => LiteSpeed V6.1
Virtual Directory Support => disabled
Configuration File (php.ini) Path => /home/mike/lsws/lsphp5/lib
Loaded Configuration File => (none)


So.. PHP seems to be installed correctly , but LiteSpeed isnt handeling the PHP mime type correctly (?)
=> It's probably something really stupid (I sped through this thinking I could set up a VPC, Litespeed, PHP .. and then msql/forum withing a few hours, just to test a plugin I was developing)

I like the LiteSpeed GUI by the way, and the ease of adding additional PHP packages

There is something I've noticed about the php5 folders, they seem to have root ownership (why I don't know). I'm going to try changing the permisions of the folders

Edit: nope

sudo chown -R mike:mike lsphp5/

and I still have the same issue

any message in /usr/local/lsws/logs/stderr.log ?

have you changed any of the default setting in
Server->External App->lsphp5 ?

and you can try build php 5.3.21 with minimum size:
Configure Parameters:--disable-all

to see if phpinfo() show up.

The stderr.log message is in the first post (its the same every time I visit the default PHP page)

I've left the default settings, I just had a look at these and they are set to:
LSAPI App lsphp4 uds://tmp/lshttpd/lsphp4.sock
LSAPI App lsphp5 uds://tmp/lshttpd/lsphp5.sock

I'll try php 5.3.21 with minimum size now

I still get the error message

PHP 5.3.21 (using only --disable-all) compiled without error:
**MAIN_STATUS** retrieved from /home/mike/lsws/phpbuild/buildphp_1361813196.8.progress
Start building PHP 5.3.21 with LSAPI
Configuring PHP build (2-3 minutes)
Compiling PHP (5-10 minutes)
Installing PHP
copy compiled php binary to litespeed directory
**COMPLETE**
Click to expand...
But navigating to the default (or any) PHP file still results in the 503 error

1)try if php 4 work:
Server->Script Handler->Suffixes: php->Edit->Handler Name:lsphp5->lsphp4,
then restart lsws

You should change soft/hard process limit in LSPHP5 external app (Admin Console => Configuration => Server => External App => LSPHP5) instead.
