Re: [users] eth0 Down not detected

[A V M. <mah...@or...>]

Hi Nivrutti,

Try with tune keepalive  configuration  of /etc/opensaf/dtmd.conf , by 
the way which linux distribution you are using ?

Uncomment the  line  "args="--tracemask=0xffffffff" to enable trace in both
/etc/opensaf/dtmd.conf  & /etc/opensaf/amfnd.conf and send 
/var/log/opensaf/osafdtmd  & /var/log/opensaf/osafamfnd  traces.

-AVM
