We have a PHP application that has 3 web servers (running Nginx and Apache). The web server's directory root are symlinked directories that point to an NFS mount. For example:
web01 has an NFS mount at
/data/webapp, which is symlinked to
/home/webapp. Apache serves content from
We also use
ACP for our PHP opcode cache. When we deploy code, we SCP an archive file to the NFS server and extract it.
Since upgrading RedHat 6, when we deploy our code the webserver execute "stale" PHP files until
touch is run on the PHP files. We thought that
APC might be causing a problem, but the issue exists, even after clearing the opcode cache.
Any ideas on how to diagnose why the stale PHP code is being executed?
