Because you have to few RAM? Clamav needs 2gb alone.

Yes, it's out of memory!
I have enabled all IDS  rules for the test.
Perhaps there is a recommendation for the minimum settings for the IDS rules?

Exactly the same error, but IDS works.

the error disappears after deletion
rm -rf / usr/local/etc/suricata/

BUT!  >:(
IDS stops working immediately after enabling ClamAV + ICAP.
