Webalizer still runs for already an hour. Memory, CPU and disks are OK. The reason for such long operation is extreemly big web.log files. I have sites in my server that have over 150MB web.log files. But I monitor it now, while webalizer script runs and I don't see anything strange.

I may move the cron.daily to run later in the morning, so I could be there and look at the console output. Because now the screensaver prevents me from seing the output.
