Aye, the travel and action issues stem from the server instability which appears to be caused by the load that travel is having to cope with. We've had a monitoring script in place for a while that will take the server down and restart it if things gets too heavy, but the best that can do is minimise downtime. We're looking at throwing some more hardware at the server and hope to be able to put some resources into redesigning travel to cope with the large load it is trying to deal with.
There's already a button of sorts that kicks the travel script into gear again that people with high enough server access can hit. When that's the cause of it it's just a matter of such a person being on to do it when the server reaches the load limit.
