I confirm I see same on the agmini system. Two problems: (a) error message is wrong, it's a
short read, not a read error (clue: read() syscall does not return "no such file"). (b)
mlogger is supposed to write history in record-size blocks, read in the same record size

I started to get web browser popups about "midas wants to show notifications,

04:17 - [mhttpd,ERROR] [history_schema.cxx:2913:FileHistory::read_data,ERROR] Cannot read

Confirmed. The error message is wrong. It is printed after a short read(), but short read() does not
set errno, and errno reported by the error message is from some previous syscall. Corrected error
message is already committed. K.O.

The epics frontend overwrites the "start command" odb after each start:
// set start command in ODB

Thanks for reporting this problem. It has been fixed today, so the start command is only written if it's emtpy.

Thanks for the bug report Gennaro!
I've fixed the code so that we'll now find the end-of-run ODB dump even if the user is already at the end of the file when they call get_eor_odb_dump().
