We see Evolution do the DAV PUT and there is an immediate create response from Zimbra. However, Zimbra then waits 75 seconds before issuing a FIN to close the TCP session. Only then does Evolution do a DAV GET (I assume to confirm creation).
In the meantime, we see the Evolution client trying to issue a FIN to the Zimbra server but it is for a seemingly different connection (different ACK and SEQ numbers). In fact, we see Evolution issue this FIN,ACK before it starts creating the appointment. I do not know if it is related. In the meantime, we see the Zimbra server trying to issue RST for these ACKs as it has no associated TCP connection (I assume). Since we have a firewall between the users and the Zimbra server, these resets are being dropped as they are not associated with any existing TCP connection. I'm going to allow that traffic in a few minutes and see if it eliminates the delay. I don't know where these stray FIN packets are coming from but they seem consistent. Regarding Evolution versions, here's what I have: evolution 2.28.3-1+b1 evolution-common 2.28.3-1 evolution-data-server 2.28.3.1-1.3 evolution-data-server-common 2.28.3.1-1.3 I have gnome-icon-theme 2.30.1-1.
