Client disconnected (FD 10) after starting clamonacc

[wforumw]

Describe the bug

We have installed the latest version of clamav.
We use clamonacc to use ClamAV's On-Access Scanning feature. After starting the clamonacc daemon we get thousands of Client disconnected (FD 10) in syslog.
But it seams that On-Access Scanning is working. We have tested it with an eicar test file and get
eicar-test.txt: Win.Test.EICAR_HDB-1 FOUND in syslog

Why is syslog filled with with thousands of messages Client disconnected (FD 10) in a very short time?
