Hi, I remember that running my own scanmonitor (which also does button handling) I observed strange behavior when running against my cheap plustek backed Epson scanner. The issue was also high CPU load and I never found out why, what I know is that other scanners like the Fujitsu fi-6x series never had such problems. Maybe this is related here with scanbd and the genesys backend?
