It seems you can't trap any connection errors with this component. If the server isn't listening, the POE::Kernel->run() in the client crashes. The code is trying to parse an HTML error message when it's expecting a JSON string. bash-3.1$ perl ./BayeuxClient.pl Failed to JSON decode data (error malformed JSON string, neither array, object, number, string or atom, at character offset 0 (before "<html>\n<HEAD><TITLE...") at /arm/tools/perl/perl/5.8.8/common/lib/site_perl/5.8.8/JSON/Any.pm line 481. ). Content: <html> <HEAD><TITLE>Error: Internal Server Error</TITLE></HEAD> <BODY> <H1>Error: Internal Server Error</H1> Cannot connect to 127.0.0.1:80 (connect error 111: Connection refused) <small>This is a client error, not a server error.</small> </BODY> </HTML> This is using your example from the perldoc. Specifying an 'ErrorCallback' doesn't work. Neither does trying to trap the kernel 'DIE' signal. Of course, I could have missed something. I'm new to this POE malarky.
