srdo commented on issue #2993: STORM-3374 remove unnecessary stacktrace from log URL: https://github.com/apache/storm/pull/2993#issuecomment-480277317 Thanks. Maybe we could log the stack trace at debug or trace level, and keep the info level log without a stack trace? The reason I'm worried about removing it is that the exception handler catches any kind of exception coming out of the Netty channel handlers, so I don't think we can be sure the exception is innocent. Alternatively we could log IOExceptions at info level without stack trace (with stack trace at debug/trace level maybe), and any other type of exception at error level?
