Request for review of various error messages that one sees in logfiles #135

Open bieryAtFnal opened 1 year ago

bieryAtFnal commented 1 year ago

There are at least three different types of "error" messages that we occasionally see in the RU logfiles. It is hard to know whether these are really errors that a user should be worried about. And in some cases, it is not clear why the message is not being reported with an error status. I've seen these errors when using emulated-data systems.

It would be great to understand what these errors mean and, if needed, change their reporting appropriately.

Something is wrong with the FE source or with the configuration!

The first one has been discussed before, so maybe we just need to implement a known change.

I filed an incremental PR for the second one, in which I added more information about the type of error. It is easy to reproduce with certain WIBEth asset files and the minimal_system_quick_test.

I noticed the third one when testing a software area based on v4.1.1.

On the dunedaq-integration Slack channel, Michal Rigan posted the following:

Dunno if this is known, but I'm doing some offline development and I often get this error from ru: 2023-Sep-05 11:54:52,995 LOG [void dunedaq::fdreadoutlibs::WIBEthFrameProcessor::sequence_check(frameptr) at /tmp/root/spack-stage/spack-stage-fdreadoutlibs-NFD23-09-04-4ijcp6hukfsdxe3iagfnnr4y67lca35u/spack-src/src/wibeth/WIBEthFrameProcessor.cpp:393] Data Integrity ERROR Sequence ID continuity is completely broken!
