Bug #71574 [NEW]: Opcache corruption after using opcache_reset()
From: ruudk at mphuis dot com
Operating system: Ubuntu 14.04.3 LTS
PHP version: 7.0.3
Package: opcache
Bug Type: Bug
Bug description:Opcache corruption after using opcache_reset()
Description:
------------
Sometimes, after running a deploy using Capistrano and clearing the
Opcache using a curl request that executes opcache_reset() we get loads
of 500 Internal Server errors.
In our error log we see something like this:
[12-Feb-2016 08:45:31 UTC] PHP Fatal error: Class
'CartBundle\Service\PaymentService���' not found in
/company/releases/20160212084602/cache/prod/frontendProdProjectContainer.php
on line 7805
It's never the same class that's missing, it's never the same server
that has the problem. It occurs random.
The solution is always to execute the opcache_reset() again or to
restart PHP FPM.
Some more errors:
[10-Feb-2016 15:33:10 UTC] PHP Fatal error: Class
'Monolog\Handler\AbstractProcessingHandler���' not found in
/company/releases/20160210153329/cache/prod/classes.php on line 1111
PHP Warning: include(): Failed opening
'/company/releases/20160209133021/vendor/richsage/rms-push-notifications-bundle/RMS/PushNotificationsBundle/RMSPushNotificationsBundle.php�php'
for inclusion (include_path='.:/usr/share/php:') in
This one is also remarkable, because you see lots of weird characters in
the filename.

So to me it appears to be a race condition that corrupts the opcache. We
run 2 of 3 webservers behind a loadbalancer with a couple of hundred
people online simultaneously.
We use the following opcache settings (rest is standard):
[opcache]
; Determines if Zend OPCache is enabled
opcache.enable=1
; The OPcache shared memory storage size.
opcache.memory_consumption=192
; The amount of memory for interned strings in Mbytes.
opcache.interned_strings_buffer=16
; The maximum number of keys (scripts) in the OPcache hash table.
; Only numbers between 200 and 100000 are allowed.
opcache.max_accelerated_files=32531
; How often (in seconds) to check file timestamps for changes to the
shared
; memory storage allocation. ("1" means validate once per second, but
only
; once per request. "0" means always validate)
opcache.revalidate_freq=1
It looks to be related to https://bugs.php.net/bug.php?id=70656 which is
closed/solved.
