Error Clamav

Hi, I'm new to this forum.

I'm trying to setup a small NAS here. I installed the OMV and the Clamav plugin on a test machine and apparently it workred.
However, when I installed OMV on the "real" server machine, I got this error when tring to run a job on Clamav:

Please wait, scanning shared folder <Teste> ...

ERROR: Could not lookup : Servname not supported for ai_socktype

----------- SCAN SUMMARY -----------
Infected files: 0
Total errors: 1
Time: 0.000 sec (0 m 0 s)

When I click "Services" I see the antivirus enabled, but the little ball is red, instead of blue.

What could be wrong ? I already installed OMV twice, and I also tried to unintsall and install the plugin again. But none of them worked, and the error remains.

Sorry, but I am not a linux expert. I did not understood much of what you said.

I don't know what happened, but after several restarts . The little ball turned blue and the AV is working.
