Intermittent "Application Failed to start" errors

In my project everything is working fine except from time to time I keep
getting the error: “Application failed to start”.

After refreshing, the error goes away.

Why I am getting this error and what’s the best way to avoid it?

Thanks
Frank
P.S. I am using Apache 2 with dispatcher.fcgi on RHEL 3

i have found this to happen when using process/reaper -a reload

The first request or two seem to really get messed up (same errors as
you), but then everything is fine. No explanation just some
comfirmation that you are not alone here…
