LSAPI Sockets Closing Periodically

[Ghan_04]

I am having an issue where I have a few sites setup using PHP with the LSAPI external app. Each one has its own external app config so that I can use suEXEC and have each site run its own PHP processes. However, since switching over to this config, I am finding occasional 503 service unavailable errors with this showing up in the error log:

The lsphp.sock files appear to be getting closed and vanishing periodically so that they have to be restarted. I am also seeing lots of these statements in the log:

2012-02-19 04:10:12.000 [INFO] [CLEANUP] Clean up child process with pid: 5229
2012-02-19 04:10:12.000 [INFO] [CLEANUP] Clean up child process with pid: 5231

2012-02-19 04:10:22.008 [INFO] Remove pid: 5260, exitcode: 0

I have the external app set to auto start and run on startup with persistent connections turned on.
Any ideas how I can resolve these errors?

Thanks!
