Get rid of "%AMDP2_FE-6-EXCESSCOLL" Error in IOU L2 Image

L2 IOU Images always pop up this error frequently saying %AMDP2_FE-6-EXCESSCOLL as shown below and it's really annoying to work with L2 image. I am using IOU image on Unetlab (UNL).









To get rid of this error, many places on internet says to enter following lines manually to each and every device which did not work for me.

logging discriminator EXCESS severity drops 6 msg-body drops EXCESSCOLL
logging buffered 50000 
logging console discriminator EXCESS

But the real solution to stop it was to edit sysctl.conf file in virtual machine with a one line of code.

SSH to virtual machine on VMware.

Enter the following command to edit the file
nano /etc/sysctl.conf

Go to the bottom of the file and paste the following lines
# Get rid of  %AMDP2_FE-6-EXCESSCOLL Error
net.unix.max_dgram_qlen = 2000000 























Hit Ctrl+X to exit and hit Y to save for the same name.

Restart the Machine
sudo reboot

Now it will not come again. I don't know whether high CPU or a Loopback traffics causes this issue. But it just worked for me this way. Hope this will be helpful to someone.
