hi,
the ci-cd shaked out a race condition in the polka and mpolka implementations
this night,
https://github.com/rare-freertr/freeRtr/commit/eb86a187d2733bb90505fcc5c7a088fa5b421de4
is the fix,
please update your boxes... the mpolka part was more dangerous but the
regular polka one was also buggy...
br,
cs
