It has good tips on how to collect and report information.

Second, I recommend that you pastebin your relevant portion of the dialplan
and the whole javascript program that you are using so that others can take
a look.

Last thing: if you restart FreeSWITCH does everything work fine for a while
but then eventually it breaks down and exhibits the behavior that you are
reporting?
