[Olsr-users] Unusual Delays between LQ Hello message transmissions

[Joe Pulver]

I thought I posted this on Friday, but I can not find any record of it 
in the archive.  If this is a repost, I apologize.  I'm still stumped by 
this behavior.

I'm seeing some unusual gaps in the transmission of LQ Hello Messages.  
Even though I set the Hello Interval to 0.5, I am occasionally seeing 
2-3 second delays between LQ Hello messages (tcpdump on the sending 
node).  Most of the hello's do go out at 2 Htz, but some take 2-3 
seconds.  During the 2-3 second gap the TC messages are going out as 
scheduled, and the OLSR sequence numbers on the outgoing packets show no 
packet loss. 

I'm running OLSR-0.5.6, under Linux on a WRAP board.  I'm using the 
configuration file "files/olsrd.conf.default.lq" with the following 
modifications.  Thank you in advance for any assistance from the list.

Pollrate 0.02                 #was 0.05
HelloInterval 0.5           #was 2.0
HelloValidityTime 5.0   #was 20.0
TcInterval 1.0              #was 5.0
TcValidityTime 10.0    #was 30.0
