You can use Gmane or Google to search the archives
Ah, didnt know Gmane yet, usefull service.
Not finding it via google was my own fault, my search query was to specific.
both are documented in docs/FAQ.
Ok, I have now found your FAQ when noticing your email address. Perhaps you
can convince the maintained of ntop.org to refer to your updated FAQ? Might
safe some emails on the mailinglist ;)
Read the stuff in the archives and docs/FAQ on self-LOCKED - it will give
you a basis for the discussion.
Okay, that gave me some idea on what these warnings are about. For now I
added --disable-mutexextrainfo to my ntop.conf for I cant find yet on how to
force ntop to a single CPU yet. That seems like a shame anyway, having 2
dual core CPU's and restricting ntop (one of the most resource hungy
processes on the system) to a single CPU.
I am still experiencing the slow web-interface at times, I guess it's
'collides' with a hash flush or some other update from ntop, trying a couple
of seconds later it loads okay again.
Thank you for your patience and time, and I'd like to say you did quite a
nice job on the FAQ.

From: "Burton Strauss" <[EMAIL PROTECTED]>
Read the back traffic on ntop - it's a multiple threaded app.
My bad, didnt know this.
On reading back; I just joined the list, and the webarchives dont provide
a
search function, so 'reading back' isnt very feasable imho.
Self-locked really shouldn't happen in 3.2, although it's just a
warning -
Well, apparently it does happen :)
What does this self-locked actually mean for me? Will I loose the data
concerned? Will it be queued?
And more important; Are there any pointers on what is causing these
errors?
usually the data at risk is only the locking data itself.
If it would occur a couple of times a day I would not be very concerned,
but
my logs are really filling up with these errors. I guess there is a decent
amount of data at risk
As a test, you can try using
the OS to restrict ntop to one processor (if it will allow you to do so).
I'll look into this on monday when I have access to the server again.
NTOP is also having peaks of 90% CPU load, this also doesnt seem very
normal
to me?
tia for your time.

Subject: [Ntop] queuePacket/dequeuePacket errors
Hello,
I am having some troubles with running NTOP on a 100Mbit network with
quite some traffic to monitor. A short while after starting up the
process the webinterface becomes sluggisch and unresponsive at times.
When I check /var/log/messages I am seeing a flood of the errors below
repeating
**WARNING** tryLockMutex() called 'queuePacket' with a self-LOCKED
mutex [EMAIL PROTECTED]:2219]
**WARNING** accessMutex() called 'dequeuePacket' with a self-LOCKED
mutex [EMAIL PROTECTED]:2399]
NTOP is also spawning multiple processes, at the time of writing I am
up to
9 NTOP processes, running for a small 5 minutes now.
I recon NTOP cannot keep up with the traffic or the amount of hosts
and their data, are there ways to tweak NTOP? I figure the machine
itself is not the problem, since it concerns a dual Xeon 2.4Ghz, 1Gig
of RAM with a SCSI harddisk.
