I've edited that line, so we'll see if it happens again, and if it does
I'll relay the information back to you.

Well, something interesting, though perhaps unrelated - when I created
the profile via the web interface the first few capture files were owned
by the apache user and group, but when I restarted the nfcapd the next
time via the init script the files are owned by netflow user and apache
group, the group has read access, while the user has read write access.
I'm keeping 35 days of data presently for each profile, so it should not
be attempting to expire anything yet.

Other than that the box is still in testing (probably until the end of
the month, when I'll switch our accounting over to nfsen/nfdump from
September - I'm the only one with access to the box, and from that no
one would have been making any changes at that time in the morning.

I'm glad to hear it, perhaps it was just a blip. Any info I get I'll let
you know.

One other thing, I notice that the dump files are relatively
uncompressed - would that be a feature that might be implemented in the
future? Another option would be to use a compressed filesystem to store
the files on, does such a filesystem exist under Linux?

Many Thanks
