<p class="MsoNormal">Hi everyone, <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-GB">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.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">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.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">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. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Has anybody experienced similar behaviour before and has a hint on possible causes or fixes?<o:p></o:p></span></p>
