How long it waits before giving up on an action.
You might see things like:
-failed on WinHttpReceiveResponse
-SendMessage RpcException The request has timed out.
-Rpc::HandleConnectionFailure.
Timeout options
--connect-timeout,-tc <ms> : connect timeout in miliseconds.
--send-timeout,-ts <ms> : send timeout in miliseconds.
--receive-timeout,-tr <ms> : receive timeout in miliseconds.
--option-receive-timeout,-tor <ms> : option receive timeout in miliseconds.
All those values should be greater than 60000; if less, 60000 is automatically used.
Unless of course you choose to edit the sections like:
if(iValue < 60000) iValue = 60000;
Though logic like that is generally there for tried and tested reasons.
You can also edit these later via the registry:
HKCU\Software\Zimbra\Connection\Timeout
Bug 10669 - connection timeout should be configurable in the registry Bug 15663 - allow config of connection timeout values with ZmCustomizeMsi.js
