This causes reading until the End Of File of PIPE, then you process all lines.

Instead, I suggest you try:

while ( <PIPE> ) { # do some stuff }

[ Syslog-NG opens a pipe to your program when it is started and closes it when it's stopped. It doesn't open a new pipe for each log line. ]

Thanks, I understood this was the case for a pipe as in two commands with a | but didn't know it kept a fifo open too. Should have guessed this from the behaviour. Thanks, Jim Mozley
