[Ntop] best OS for ntop? (freebsd problems)

[Mike Lambert]

I am having several problems running ntop 3.2.3 (2 Nov) on generic, unmodified FreeBSD 6.2-PRERELEASE. Attempts to build from current cvs fails with several gcc "linker input file unused because linking not done" errors. Is there a best OS to build and run ntop on?  Any/all suggestions appreciated.

Problem details:

Problem #1
Ntop will run for several days, then crash (sig 11). Ntop then only runs for a few minutes before crashing. Deleting /var/run/dnsCache.db will allow ntop to run "normally".

Problem #2
Ntop will consume 100% CPU and not answer web requests. Restarting shows strange traffic graphs indicating one or more traffic rrDBs became corupt. Deleteing /var/ntop/rrd/interfaces/xl0/* returns normal behavior.

Problem #3 (may be same as #2)
Ntop consumes 100% CPU. The following error was printed to the shell that started ntop...

  "Assertion failed: (lu->lu_myreq->lr_watcher == ((void *)0)), function _lock_acquire, file /usr/src/lib/libpthread/sys/lock.c, line 170."

Problem #4
Ntop hostsInfo, sortDataProtos, sortDataIP attribute wrong hosts to bandwidth usage. No errors on console or logs. CPU usage normal. Re-starting ntop solves problem.
