Created attachment 9 [details] Patch The way the function start_slon in slon-tools.pm assembles the command line creates a command that looks like this: slon ... 2>&1 >logfile & This ends up dumping the error messages on the console (or wherever) and only stdout to the log file. What you want is this: slon ... >logfile 2>&1 & The attached patch fixes this.
