[Swift-devel] Re: coaster-service -passive null pointer exception

[David Kelly]

Hey Mihael,

I was testing my script a little more today and ran into some errors related
to CONFIGSERVICE. In this example I was testing passive mode but manually
specifying ports instead of using the port files. I'm not sure if that makes
a difference - I included an output of ps so you could see how each of the
apps were being called. There is more detail in the swift log and in
logs/coaster.log.

Thanks,
David
