I've got concurrencylocal set to 50, and concurrencyremote set to 40. However, looking at my MRTG graphs created by qmail-mrtg from prodigysolutions, it would appear something is limiting concurrency to 30. The maximal 5 minute plot (magenta, remote I believe) is almost flat against 30 for most of the day, and the blue line never goes above it. Am I missing something, or is qmail-mrtg? Hmmm... it is v 1.0. Maybe I'll upgrade. jon
