Errors with stack traces

[acanimal]

Hi,
I'm using winston with console and syslog transports. While errors on console are shown with stack traces like:

error:  Error: dummy error
    at expressApp.use (/Users/someuser/Psomeporject/server/server.js:78:12)
    at Layer.handle [as handle_request] (/Users/someuser/Psomeporject/node_modules/express/lib/router/layer.js:95:5)
    at trim_prefix (/Users/someuser/Psomeporject/node_modules/express/lib/router/index.js:317:13)
    at /Users/someuser/Psomeporject/node_modules/express/lib/router/index.js:284:7
   ...

Our syslog server is configured to store error leveled messages in an error file, the problem is with the previous error only the first line is stored in the error file, while the rest of the info is written in an accesslog file.

Any help will be appreciated. Thanks.
