Hi,
Could you check that
- DLS and the data sources are synchronized with NTP
- your NTP server works

Hi everyone,
we are experiencing weird data losses on the DLS. Everything works as
expected for a couple of hours. Then, suddenly, there is a message in
the logs from dlsd_logger declaring an unexpected high time difference
in a number of channels followed by a message that the msr protocol was
reset by the peer and dls stops logging with error code -2. Logging is
continued after the preset 30 seconds, but typically crashes again
shortly after.
I am quite at loss how to proceed, there is nothing apparently wrong –
the same system set-up has worked up to now, there is nothing unusual in
the logs and system load (disc, cpu, network, ram) appears normal. The
error appears on several systems, the only common thing appears to be a
certain hardware configuration (certain somewhat older fujitsu
desktops). Unfortunately, I do not have enough other hardware at hand to
really support that theory.
We work with openSUSE and installed our etherlab environment from the
science:EtherLab repository using the generic network driver. We see the
error on 15.2 and 15.3 systems, but haven’t managed to check 15.4 yet.
Has anybody experienced similar behaviour before and has a hint on
possible causes or fixes?
All the best,
Amos
