Hi Andrew, In my case it failed several times and appeared to be triggered by seemingly harmless code changes, but it seemed like the problem was reproducible for a given version of the code. What seemed to matter was when I changed things related to local variables inside the set_ipfix_exporter_command_fn() function. The test logs said "Core-file exists" which I suppose means that vpp crashed. The testing framework repeats the test several times, saying "3 attempt(s) left", then "2 attempt(s) left" and so on, all those repeated attempts seemed to crash in the same way.
It could be something with uninitialized variables, e.g. something that is assumed to be zero but is never explicitly initialized so it can work when it happens to be zero but depending on platform and compiler details there could be some garbage there causing a problem. Then unrelated code changes like adding variables somewhere making things end up at slightly different memory ocations could make the error come and go. This is just guessing of course. Is it possible to get login access to the machine where the gerrit/jenkins tests are run, to debug it there where the issue can be reproduced? / Elias On Wed, 2020-05-27 at 19:03 +0200, Andrew 👽 Yourtchenko wrote: > Yep, so it looks like we have an issue... > > https://gerrit.fd.io/r/c/vpp/+/27305 has the same failures, I am > rerunning it now to see how intermittent it is - as well as testing > the latest master locally.... > > --a > > > On 27 May 2020, at 18:56, Elias Rudberg <elias.rudb...@bahnhof.net> > > wrote: > > > > Hi Andrew, > > > > Yes, it was Basic LISP test.
