Note
babeld
can spew out massive amounts of route changes that can fill the
netlink socket. rmon
tries to allocate a 16MB receive buffer, which seems to
be enough for the moment. For this to work check /proc/sys/net/core/rmem_max
to be more than 16MB (16777216).
Set receive buffer size temporarily
Do one of the following:
# echo 16777216 > /proc/sys/net/core/rmem_max
# sysctl -w net.core.rmem_max=16777216
Set receive buffer pemanently
Add the following line to /etc/sysctl.conf
:
net.core.rmem_max = 16777216
and run
# sysctl -p
