The NumberFormatException here is probably the result of a String value that cannot be parsed into an integer. It seems likely this is a bug in your program code, not a service issue.

Moving this to...hm...well I'll figure it out in a sec.

[Ilja Preuss]

There seems to be an "n" in your configuration where log4j expects a number.
