Hi, Running 3.1.12.1 on Linux.. I have recently ran into situations where squid appears to be creating an empty PID file. I have not yet determined exactly how to reproduce the problem and it seems to occur rather randomly. When this happens, squid is running and all seems ok, but things like 'squid -k check' fail because they cannot find the PID. Again, the file _is_ created, but it is empty. Has anyone seen this before. Any idea what could be causing this? Thanks! John Craws
