"Anatol Belski" in php.windows (Mon, 8 Jul 2013 18:54:30 +0200): >You can try to run from another user account, then the mmap filename will >change. When I saw the name ZendOPcache.MemoryBase@Administrator I already was thinking about such a solution. That must be possible with mote than one instance of Apache, but I do not see how it could be possible with several PHP's under 1 Apache. Running Apache as 1 user and PHP-CGI as another user is bound to lead to problems (if it is possible at all). >From the OPcache readme: opcache.mmap_base Mapping base of shared memory segments (for Windows only). All the PHP processes have to map shared memory into the same address space. This directive allows to manually fix the "Unable to reattach to base address" errors. Could this be a way out? It looks like this setting overrides the setting in ZendOPcache.MemoryBase. What I want is that the OPcache of PHP 5.5 does not share the memory with PHP 5.3. Can that be reached by setting one mmap_base to 20000000 and the other to 30000000 (or something like that). If you think this is possible, what would the settings be for opcache.mmap_base of both PHP instances?
