spam acl condition: cannot parse spamd output

I have the same behavioral like in post https://community.sophos.com/utm-firewall/f/mail-protection-smtp-pop3-antispam-and-antivirus/113734/does-your-spam-check-have-intermittent-failures 

spam acl condition: cannot parse spamd output
Warning: ACL "warn" statement skipped: condition test deferred

We have a 2 Node HA System (Active-Passive). When this happens, its not often, SPAM is not filtered and gets to users inboxes. In case it happens, we must reboot the active Node so that the Standby-Node gets active and the the Spam-Filtering is working again. What can cause the error? Maybe the spamd deamon runs out of memory like here described: https://forums.cpanel.net/threads/exim-and-spamassassin-fails-spam-acl-condition-cannot-parse-spamd-output.376581/ ? where can i find the spamd log files?

This is a annoying Bug which must be resolved!

Greetings
