No, you're misinterpreting the message.  What that code likely means
is that something is trying to use SPI and finding plpgsql already
connected.  In other words, plpgsql forgets to do a SPI_push() before
calling something that might try to use SPI re-entrantly.  It should be
perfectly deterministic and it definitely doesn't have anything to do
with the states of other sessions.  But we're going to need a test
case to fix it.
