Thanks. ------------------------------------------------------------------------ [2017-10-15 12:53:33] tm8544 at hotmail dot com Eventually 'Warning Internal error: wrong size calculation' appered into the log again, so it was not about config options. ------------------------------------------------------------------------ [2017-10-15 11:17:37] tm8544 at hotmail dot com The first comment led me thinking that after all, what if it is about an already cached script? I my PHP.ini some opcache config options were commented out, so they were in their default values. I changed this so that I specifically gave those options the default value. For opcache.file_cache_consistency_checks I also changed the value, even though file_cache is not used. Here are all config options, changed lines are marked with ***, left is the new value / right is the old value. opcache.enable=1 / opcache.enable=1 opcache.enable_cli=0 / opcache.enable_cli=0 opcache.memory_consumption=128 / opcache.memory_consumption=128 opcache.interned_strings_buffer=8 / opcache.interned_strings_buffer=8 opcache.max_accelerated_files=4000 / opcache.max_accelerated_files=4000 *** opcache.max_wasted_percentage=5 / ;opcache.max_wasted_percentage=5 *** opcache.use_cwd=1 / ;opcache.use_cwd=1 opcache.validate_timestamps=1 / opcache.validate_timestamps=1 opcache.revalidate_freq=60 / opcache.revalidate_freq=60 opcache.file_update_protection=3600 / opcache.file_update_protection=3600 opcache.revalidate_path=1 / opcache.revalidate_path=1 opcache.save_comments=1 / opcache.save_comments=1 opcache.load_comments=1 / opcache.load_comments=1 opcache.fast_shutdown=0 / opcache.fast_shutdown=0 *** opcache.enable_file_override=0 / ;opcache.enable_file_override=0 opcache.optimization_level=0xffffffff / opcache.optimization_level=0xffffffff *** opcache.inherited_hack=1 / ;opcache.inherited_hack=1 *** opcache.dups_fix=0 / ;opcache.dups_fix=0 opcache.blacklist_filename=c:\PHP\php.ini.opcache_blacklist.txt / opcache.blacklist_filename=c:\PHP\php.ini.opcache_blacklist.txt *** opcache.max_file_size=0 / ;opcache.max_file_size=0 *** opcache.consistency_checks=0 / ;opcache.consistency_checks=0 opcache.force_restart_timeout=15 / opcache.force_restart_timeout=15 *** opcache.error_log="" / ;opcache.error_log= opcache.log_verbosity_level=2 / opcache.log_verbosity_level=2 *** opcache.preferred_memory_model="" / ;opcache.preferred_memory_model= *** opcache.protect_memory=0 / opcache.protect_memory=0 *** opcache.restrict_api="" / ;opcache.restrict_api= opcache.mmap_base=0x20000000 / opcache.mmap_base=0x20000000 *** opcache.file_cache="" / ;opcache.file_cache= *** opcache.file_cache_only=0 / ;opcache.file_cache_only=0 *** opcache.file_cache_consistency_checks=0 / ;opcache.file_cache_consistency_checks=1 *** opcache.file_cache_fallback=0 / ;opcache.file_cache_fallback=1 *** opcache.huge_code_pages=0 / ;opcache.huge_code_pages=1 *** opcache.validate_permission=0 / ;opcache.validate_permission=0 *** opcache.validate_root=0 / ;opcache.validate_root=0 After this, I have not seen any warning of wrong size calculation in Apache log. Could it be that PHP7.2.0 handles opcache config option default values differently than e.g. 7.1 or previous versions? ------------------------------------------------------------------------ [2017-10-15 06:28:20] tm8544 at hotmail dot com In this case, I believe it is not a about replacing an already cached script. It happens even when the server is restarted, so there should be no cached scripts in memory. It is always those three scripts, values for 'start', 'end' and 'real' change from time to time ------------------------------------------------------------------------ [2017-10-13 18:14:19] spam2 at rhsoft dot net I faced this "internal size error" randomly after upgrade to php 7.1.x in production but can't trigger it reliable - when it happens it is always after replace a already cached script ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
