--- Comment #16 from TM <tm...@del.bg> ---
I'm hitting this behaviour if I enable the shortcircuit plugin, which is the
default with SpamHaus recommended configs from
https://github.com/spamhaus/spamassassin-dqs
The exact error message is:
bayes: cannot open bayes databases /%PATH%/.spamassassin/bayes_* R/W: lock
failed: Interrupted system call
Here's the process and fd situation at the time:
# ps axfuww|grep spam

Disabling Mail::SpamAssassin::Plugin::Shortcircuit in sh.pre resolves the
problem. Without shortcircuit things look like this:
