I am experiencing a strange issue with our FileMaker 12 server. It is not correctly closing XML (and to a lesser extent PHP) connections.
Even after simple queries are finished, the fmxml connections are still showing in the client list for the file. Once there are 2 or more of these users 'connected' the web publishing engine appears to completely freeze up. Restarting the WPE or manually disconnecting those web clients resolves the issue.
I have noticed the same problem happening even with the FileMaker PHP technology test page. It will keep a FMPHP connection open. This is not a result of just seeing long queries process, because the pages in question are fully loaded, so the CWP connections should close.
Any suggestions on what may be causing the issue?
