[clamav-users] clamav "Can't unlink file ERROR"

[An Schall]

Hi all,

we are trying to get clamscan / clamdscan functional on a RHEL with
GPFS as a filesystem. We are using clamAV 0.104.2. On a different test
machine everything works like a charm. However, on this specific RHEL
machine, we get the following errors:

# clamdscan -v --config-file=/etc/clamav/clamd.conf --multiscan --fdpass ./
/global/mmds/test/platform/antivirus/antivirus/yes-virus/dissemination-benchmark-file-set-plus-virus.zip:

libclamav reports something about ""cli_unlink" failure no such file
or directory".

Here is the clamd.conf:

What is the underlying reason of this error message?
