Daniel Xu commented on TS-5056:
-------------------------------
I think {{Emergency()}} should only be called in very obvious and dire
circumstances. In the worst case, it should save some CPU cycles.
We're currently tracking a problem at Y! where it would be useful to have TM
not try to constantly restart TS. The new {{Emergency()}} call should be put to
use soon^tm.

> There should be a mechanism for {{traffic_server}} to signal to
> {{traffic_manager}} that {{traffic_server}} cannot be recovered with any
> amount of restarting.
> For example, if TS sees a bad log file, then no amount of restarting will fix
> TS. Thus, it would be better for TM to just sit tight and wait for human
> intervention.
