> It's not typical for a client with an active workload to wait 4400 seconds to send a fresh SYN. Bram, can you shed any light on this? The server was down for ~4400 seconds (I started the capture before the maintanance period). I captured the packets using a switch mirror port (it's possible some packets are lost during capture). After a while an arp timeout occurs and we don't capture the SYNs from the client any more (I doubt the client sends the SYN because it doesn't know where to send it). If it helps, I can filter extra information from the big pcap file (~20G) (eg capture from other clients or from the same client just before the server reboot).
