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.
