Title: NTOP Crashing
Post by: Syntax42 on Tuesday 14 May 2013, 06:32:05 am
The traffic monitor, NTOP, appears to be crashing within seconds of starting it up.  I can access the traffic monitor web page for a  seconds, but it doesn't seem to work for more than ten seconds.  Is there a known stability issue with NTOP, or is it a configuration issue?

probably memroy issue
had this issue on my vsphere, added more memory to the firewall and it works fine now!

I highly doubt I am having a memory issue.  I have 4GB of RAM in the machine.

I have looked all over the internet for a solution.  Everything I tried did not work. 

One site suggested an issue with CPU frequency scaling, but I'm pretty sure EFW Community does not have the libraries it needs to control the CPU frequency.  That means it should just run at full frequency all of the time.

I'm going to look into updating NTOP to the latest version, if it is possible.  I'm hoping the bug is not present in a newer version.

Is it a ECC memory?

Why can't you test with memtest.

It is not ECC memory.  What would ECC have to do with one program crashing?  How would a memory issue only affect one program, ECC or not?

It doesn't seem possible to update NTOP.  The versions after the ones EFW is using are for 64-bit OSes. 

I'm thinking I need to mess with some BIOS settings to improve stability by turning off certain features.  I might try a memory test this weekend, but I doubt it will help. I could run the system on just 2GB of RAM and be fine, if I have to.

I have Dell PowerEdge R300 with ECC memory
NTOP is always crashing after 5-10 minutes work, even when installed out of the box without much changes
this is always been an issue for me, during all these years and many installations

I have 2.4.1 ,
cannot install 2.5.1 because for some reason Endian removed support for my hardware since 2.5
