This are the log entries:
[hash:522] IDLE_PURGE: FINISHED selection, 19 [out of 49] hosts selected
[hash:552] IDLE_PURGE: Device 0 [eth0]: 19 hosts deleted, elapsed time
is 1,921668 seconds (0,101140 per host)

[hash:522] IDLE_PURGE: FINISHED selection, 45 [out of 90] hosts selected
At this point ntop always segfaulted.

Then I dropped the -m switch with my networks in the configuration,
since then it seems to work.

I didn't get valgrind to work right, ntop started but the webserver
didn't come up. But vmstat with 1 second intervall didn't show unusual
memory usage:
