pattern:<br>
<br>
Nova operation in progress.... takes a while<br>
Crosses keystone token expiration time<br>
Timeout thrown<br>
Operation fails<br>
Terrible 500 error sent back to user<br>
<br>
It seems like we should have a standard pattern that on token expiration<br>
the underlying code at least gives one retry to try to establish a new<br>
token to complete the flow, however as far as I can tell *no* clients do<br>
this.<br>
<br>
I know we had to add that into Tempest because tempest runs can exceed 1<br>
hr, and we want to avoid random fails just because we cross a token<br>
expiration boundary.<br>
<br>
Anyone closer to the clients that can comment here?<br>
