Hi Pablo, Pablo Neira Ayuso wrote: >>> Is the firewall sending RST packets to the peer/server to close >>> connections? If so, I remember a similar report with a RHEL kernel: I do not see any RST packets, neither on server nor on client side. I have done more tests this morning. Unfortunately, things are complicated: I repeated a basic failover test lots of times while making 1.000.000 connections. This test with 1000 parallel connections breaks every time. 500 is OK every time. The kernel only has problems with 1000 connections, and then only from time to time. In most of the cases (I guess ca. 80% of all tests), I do not need to unload/load the kernel modules, but only clear the conntrack table to get it back up running. The other times I have to reload the kernel modules in order to make the system work again. I cannot see any pattern there.
