The fix that updates the Netfilter Conntrack Sysfs variables requires
rebuilding the amphora image in order to be effective.
fixes:
- |
Netfilter Conntrack Sysfs variables net.netfilter.nf_conntrack_max and
nf_conntrack_expect_max get set to sensible values on the amphora now.
Previously, kernel default values were used which were much too low for the
configured net.netfilter.nf_conntrack_buckets value. As a result packets
could get dropped because the conntrack table got filled too quickly. Note
that this affects only UDP and SCTP protocol listeners.
Connection tracking is disabled for TCP-based connections on the
amphora including HTTP(S).
