Subject: Is megatron down? (Re: chiara local backup) 

The local backup seems working fine again. But I found that megatron is down and this is a real issue. This should be fixed at the earliest chance.


It seems that the local backup has been successfully taken this morning.

However, I noticed that the autoburt has been stalled since Dec 6 (I used to check how the backup is up-to-date using the autoburt snapshots)

Dec>pwd
/opt/rtcds/caltech/c1/burt/autoburt/snapshots/2021/Dec
Dec>ls -l

There are a bunch of errors in the log file as follows, but maybe this is not an issue

The real issue seems that megatron is down. It has a lot of house keeping jobs on corn including the N2 pressure alert.
