For all the sites that see small percentage of jobs fail with timeouts on input/output:

we are investigating interaction between rucio mover, gfal2 and xrootd. In a number of cases actual transfer was not even attempted and the reason seems to be the way rucio mover tries to stat file and get checksum. Hopefully fix will come soon, once ready we will try to get it expressly tested and deployed. This does not exclude possibility there are other issues lurking there.


It was an OK week for production.
