Hello,
Pair of LVS servers with a modified kernel worked under load for several
days without any problems.
I completed several additional tests. I analyzed the traffic to the LVS
servers using tcpdump. There is not SYN or RST packets spike at the time
of migration of IP address. Thus, most of the connections have continued
to operate normally. I also once again made sure that most of clients
remain on the same real servers.
Seems like sync_persist_mode combined with sloppy_tcp works fine.
Regards,
Aleksey
