Public bug reported:
While evaluating Wily for further use I found that after random period
of time Internet connection drops (while IP stack is configured
properly) and system message log gets quickly filled with following
messages:
Oct 07 14:06:25 hikari kernel: nf_conntrack: table full, dropping packet
Oct 07 14:06:26 hikari kernel: nf_conntrack: table full, dropping packet
Problem occurs only if I manually load nf_conntrack or related kernel
modules or start Shorewall (which loads nf_conntrack obviously).
Removing nf_conntrack and nf_conntrack and dependent modules fixes
problem and restores Internet connection.
With older builds of linux kernel (4.1.0-*) everything works as
expected.
