Found this error in one of our live sites:
2012-09-10 11:29:16.623 [error] <0.26206.307> CRASH REPORT Process <0.26206.307>
with 0 neighbours crashed with reason: no function clause
Might be something specific for the user agent, this needs to be checked.
Looks like a crash in mochiweb when a malformed request is sent. From the log files I can see that a user agent tries an HTTP request like this:
Don't think we should take any action.
I agree, if a request is malformed, then crashing is a valid end of the request.
