Hi all, I recently upgraded my server to PHP 5.5.7 with OPcache enabled. I noticed this weird behavior: After a certain period of time, I'm logged out. I use the settings recommended by PHP in opcache.ini (except consumption and buffers): Code: opcache.memory_consumption=256 opcache.interned_strings_buffer=16 opcache.max_accelerated_files=4000 opcache.revalidate_freq=60 opcache.fast_shutdown=1 opcache.enable_cli=1 I did not performed any time checks, but I think is related to OPcache. I did not changed anything else on the server except PHP. Thank you for letting me know if you had the same issues and what fix you applied.
