Code
T0029 not-current
A machine cannot answer for now. The caller may ask again.
Details
An app may run on one writer and any number of readers. A reader answers by itself only while it is current: while it has applied what its writer held at a beat that was answered no longer ago than behind of limits. This code is answered by:
- a reader that is not current and cannot reach its writer, on
/_t/healthtoo; - a reader whose writer did not take the request in time, or whose answer did not arrive whole. The error then holds
fields: { sent: 'true' }: the request may have been carried out, and a caller who must not write twice asks before it sends again; - a writer that stands back for a reader that holds more writes than it does, that holds no lease, or that was stopped by the machine that took over, for what only reads;
engine.readon an empty data folder that cannot reach its writer;app.takeOveron a reader that does not hold the whole data yet.
The fix
Ask again in a moment. Where it stays, see with tent machines which machine is the writer and whether it runs. A writer that stands back waits for tent take-over on one of the two machines.
