Well another problem.
One friend call me  that his server can’t send / receive e-mails. After I got ssh logins I see with mailq that where more then 20000 e-mail on queue.
Well I decided to remove all e-mail from queue  but how to do this.
Well the magic command is :
postsuper -d ALL
this will erase all e-mail from mailq queue
If you want to remove just one e-mail id run
postsuper -d mailID
Hope will help someone.
In the post http://matrafox.info/firephp-on-nginx-zend_db_profiler_firebug-bad-gateway.html i modiy
fastcgi_buffer_size 16k;
fastcgi_buffers 4 16k;
However after a few day I nottice that on firefox I have a lot of 502  bad gateway .  So after a short look on log I see
*62814 upstream sent too big header while reading response header from upstream
So, to fix this I increase the valuse to
fastcgi_buffers 8 16k;
fastcgi_buffer_size 32k;
I see also that they can be even higher  something like
fastcgi_buffers 4 256k;
fastcgi_buffer_size 128k;
Recently I have a huge problem. Some site stop working after a cpanel update ( we think ) .
Email client start to be slow, mysql give mysql server has gone away, some curl give us error.
After a few hour of research we find out that gethostbyaddr was the php function that kill the apps.
When we check our resolv.conf we see that one of the dns was working verry slow.
We exclude that, add google nameserver and everything was back to normal.
Also please check to not have your own server listed there.
Regards
Well because we have switch from apache to nginx we encountered a new problem .
When we have enable zend_db_profiler_firebug we got “bad gateway” error.
One simple fix for this is to append bellow line into your virtual.conf of ngix.
# set these two: zend_db_profiler_firebug
fastcgi_buffer_size 16k;
fastcgi_buffers 4 16k;
It should look something like this.
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_param APPLICATION_ENV production;
# set these two: zend_db_profiler_firebug
fastcgi_buffer_size 16k;
fastcgi_buffers 4 16k;
}
Again, try to reconfigure on another server ffmpeg, here I got another error.
/usr/local/lib/libbz2.a: could not read symbols: Bad value
/usr/bin/ld: /usr/local/lib/libbz2.a(bzlib.o): relocation R_X86_64_32S against `.text’ can not be used when making a shared object; recompile with -fPIC
After a little search I find out that on that server bzip was installed from sources not from package.
Only solution that work was to recompile bzip.
So i go into bzip directory, edit Makefile
and the line
CC=gcc
I modify it into
CC=gcc -fPIC
save the file
make clean
make
make install
And after that the ffmpeg was good to go.
