[clamav-users] Lots of "fmap_readpage" errors with ClamAV 0.99.2 on centos 7

[Ardavast Dayleryan]

Hello,

I'm running a freshly installed centos 7 box with this vagrant
image: https://atlas.hashicorp.com/centos/boxes/7
SELinux is set to disabled. ClamAV is installed from EPEL, and is running
with this configuration: https://pastebin.com/JZqPHc05

It works properly, and succeeds in detecting malicious files, however
on many filesystem operations (e.g. if I manually type "ls" in the
console),
I get errors like these in /var/log/messages which quickly fill the entire
logfile:
Jun  8 08:46:06 clamav clamd: LibClamAV Error: fmap_readpage: pread error:
Is a directory
Jun  8 08:46:06 clamav clamd: LibClamAV Error: fmap_readpage: pread error:

Is a directory
Jun  8 08:46:09 clamav clamd: LibClamAV Error: fmap_readpage: pread error:

I was not able to determine the cause by reading the source, and I'm not
sure
if this is a sign of something worse. Can someone help me understand why
is this happening and should I be worried? Any help is appreciated.
