Summary: PHP 5.5.7 and 5.5.8 horrible unstable
Status: Open
Type: Bug
Package: opcache
Operating System: Linux
PHP Version: 5.5.8
Block user comment: N
Private report: N
New Comment:
maybe the real configuration helps to reproduce
i would appreciate a unified diff for "rpmbuild" with reverts
the latest opcache changes to the state of 5.5.6 and matching
the 5.5.8 tarball to provide feedback
in the meantime i try to reproduce it with a small script instead
a large application, at the moment i am out of ideas
[zend]
zend_extension = "/usr/lib64/php/modules/opcache.so"
opcache.enable = 1
opcache.enable_cli = 0
opcache.load_comments = 0
opcache.save_comments = 0
opcache.use_cwd = 1
opcache.validate_timestamps = 1
opcache.revalidate_freq = 5
opcache.revalidate_path = 0
opcache.max_accelerated_files = 200
opcache.memory_consumption = 16
opcache.max_file_size = 262144
opcache.enable_file_override = 0
opcache.fast_shutdown = 1
opcache.error_log = "/www/_logs/php_error.log"
opcache.log_verbosity_level = 1

_________________________________________
on one of my testing-machines disable "opcache.enable_file_override" which was enabled
with PHP 5.4 all the time makes it better, on another server no way - permenently segfaults until i
stop to load opcache
the really strange is that with "ab -c 100 -n 50000" i am unable to reprocude a single
segfault, sometimes depending on luck also not with browsing, the next time nearly any request is
answered with a Firefox error that the server unexpectly closed the connection
Test script:
---------------
currently i have no easy test-script, only cms pages and complexer libraries used and as said: it
may take hours to reproduce and in other cases i update a production server to PHP > 5.5.6 and it
gets terrible unstable shortly after restart httpd
