after upgrade php-fpm always fails

[chrisf]

On every server I upgrade php-fpm fails with a message about another instance is already listening on admin.sock.

SO - I am unable to restart-all as php-fpm fails.

On my non-production servers I just reboot - but I can not do that on my production server.

What is the best resolve for this?

I tried removing the sock file, still failed.

Please advise.

What Php version used?. I didn't found this issue for php53u branch.

[chrisf]

php-fpm using 5.4u

I am not using php 5.4 and look like this version less stable compare to 5.3.

We should add something like this while restarting php-fpm:

pkill -o php-fpm;
killall -9 php-fpm;

Sometimes too:

killall -9 httpd.event;
ipcs -s | grep apache | awk ' { print $2 } ' | xargs -n 1 ipcrm -s
/script/fixphpfpm;
/etc/init.d/httpd graceful;
/etc/init.d/php-fpm restart;

php 5.4 is not less stable than 5.3 - they are on php 5.5 stable.  I agree with spacedust - killing all php-fpm processess appears to fix the problem.

Although on last update php-fpm went through - it failed on stop (which was interesting) but OK on restart?  Mustafa did you add code to update script to stop php-fpm prior to restart-all script?
