When I run mhttpd I get the following error message:

| Have you tried longer files? Maybe a few 100 MB or so. Maybe a buffer is not flushed correctly at the end of a run. |

Yes, I did. This 7 KB of the data bank is about the limit. If we go only 1 KB higher it seems that we save all data. In

I have to reproduce the problem to fix it. Why don't you go and modify midas/examples/experiment/frontend.cxx in such a way that
it creates exactly the banks you have, just with random data. If you see the same problem, send me your frontend file so that I
can reproduce it. |

Hi all,
I've ran into a problem where my experiment gets interrupted with a message from

The logger simple requests the disk free space level from the operating system in the same
way as the "df" command does. Can you do a "df" on your system? I have seen that some file
systems free up space not immediately if you delete files, but some times later (like 24h).

|
there is a problem with mlogger between commits xxx (17 Nov 2020) and a762bb8 (12 feb 2021). because of
confusion between seconds and milliseconds, FILE (mhf*.dat files) and SQL history are recording with
incorrect timestamps.
