Has anyone ever ran into a problem in which PHP's stat() call to a file on a Gluster-backed volume randomly fails, yet /usr/bin/stat never fails? Running strace against both reveals that the underlying system calls succeed. I realize this is probably a PHP problem since I cannot replicate with a non-PHP-based script; however, was hoping someone on this list might have seen this before. RHEL

The target is using an SSH destination. It ran pretty quick for a while but it's taken over 2 weeks to sync just under 1 TB of data to the target server and it appears to be getting slower. The two servers are connected
