I have not until now that you recommended it, looks much simpler indeed, thanks.
Although, so far I can't seem to hit a pipe limit. If I watch pl.stats, no matter what *timer_interval* I set, the counter increases to 1 upon a call then back to 0 the next second. root@proxy:/# watch -n 1 -d kamcmd pl.stats PIPE: id=65.39.XX.XX load=0 counter=0 Say I wanted 1 call per minute pipe, what would be the 'timer_interval' and pl_check limit?
