DON'T BID UNLESS YOU READ ALL, ESPECIALLY LAST 3 LINES
Edit typesizes.h and posix_types.h and set #define _FD_SETSIZE to 65536 and edit [url removed, login to view] to add the line "ulimit -n 32768 #" above the line "# Source function library" and recompile
First - I run PHP scripts for a living, but I do not program in PHP, I understand the basics barely. I run Ubuntu LINUX, but I also am a beginner in that as well. So we'll clarify, I'm a noob.
I run one of my PHP scripts (that opens many listening ports) and I immediately get an error - it says
PHP Warning: socket_select(): You MUST recompile PHP with a larger value of FD_SETSIZE. It is set to 1024, but you have descriptors numbered at least as high as 1024. --enable-fd-setsize=2048 is recommended, but you may want to set it to equal the maximum number of open files supported by your system, in order to avoid seeing this error again at a later date.
Machine Specs -
HP Pavilion w/A8 Quad Core processor
Ubuntu [url removed, login to view] 64 bit
Memory 8 GB
Disk Space 500 GB
I edited the [url removed, login to view] file (/etc/security/[url removed, login to view]), and added the following:
* hard nofile 70000
* soft nofile 70000
Running ulimit -a returns
core file size (blocks, -c) 0

scheduling priority (-e) 0

Somewhere, PHP is setting a 1024 limit - I need this increased to 70,000
My php also throws an error
"Undefined offset: # in /home/socksystem/[url removed, login to view]
And I assume this is related - Correcting FD_SETSIZE SHOULD fix this, but if not, I need you to take a look at it.
(Note - I have these scripts on another machine and they work. I addressed this issue previously, but I forget what I did to fix it.)
PLEASE ONLY BID IF YOU ARE A PHP EXPERT AND YOU ARE FAMILIAR WITH THIS ERROR.
DO NOT BID IF YOU THINK YOU CAN FIGURE OUT HOW TO FIX IT.
ONLY BID IF YOU ALREADY KNOW HOW TO FIX IT
