Spiking transport CPU usage may happen occasionally, usually on startup. But not that extreme. Unless you maybe enabled debug logging?

no debug logging (by the way, it would be really NICE to be able to enable and stop logging on the fly)
did reproduced today (after more 8h of run), had to stop everything
upon restart it did happen fast
will stop the service for today, will investigate tonight

again this morning (relaunched gnunet yesterday before going to sleep)
gnunet-transport is consuming 100% CPU
and
su gnunet -c "gnunet-transport -a"
No virtual links.

no "-L DEBUG" when launching (started with init.d script with "gnunet-arm -s")
but seems to create some debug log in /var/lib/gnunet/.cache/gnunet/

I attach the last, there is some data loss (run out of disk space after system update tonight) but it resumed today logs
yesterday log is available at https://filevert.fr/d/2N3IkNrzUpKoHPr6KyXw until the 11

will restart the service now that disk space is available, clean the logs and see if I can get something usefull
by the way, I've a debug build, so I can produce coredumps, but I wonder how I can do it, since this is gnunet-arm that spawn the services...
