Hong Ye was having problems with DFdaemon on his MV boxes in a M3UA configuration.
( M3UAmgr passes 10meg files across the CEs using DF… )
Eric noticed on Hong Ye’s
Monta Vista boxes that ”/sbin/ifconfig -a” cmd shows that the “txqueuelen”
parameter of each “ethx” interfaces was set to 100 whereas it is set to 1000 on other Linux machines.
Small values for txqueuelen are OK for slow device but not for Ethernet links (see ifconfig man page).
Using ifconfig cmd, Eric set txqueuelen=1000 on all “ethx” interfaces of Wilson and Roosevelt.
Everything is OK now.
It looks like txqueuelen=100 is the default for Monta Vista machines.
txqueuelen=1000 should be set by default on ALL Linux machines.
