Having the same problem in 1.8.1 on two different enviroments.

Solved by doing the same in /etc/clamav/clamd.conf
as mjaddis:
MaxScanSize 2000M
MaxFileSize 2000M
StreamMaxLength 2000M

Expected behaviour Virus scanning works for big files.
Current behaviour Virus scan failed for a 40MB file.
Steps to reproduce Settings used by Archivematica are: /usr/lib/archivematica/MCPClient/settings/common.py clamav_pass_by_stream = True clamav_client_timeout = 86400 clamav_client_backend = clamdscanner ; Options: clamdscanner or clamscanner clamav_client_max_file_size = 42 ; MB clamav_client_max_scan_size = 42 ; MB
The defaults for clamd are: /etc/clamav/clamd.conf MaxScanSize 100M MaxFileSize 25M StreamMaxLength 25M
Seems to me that for files 25M<filesize<42M then streaming will fail, which is what happened for my 40MB file (WARNING: INSTREAM: Size limit reached). I changed the clamd.conf settings for stream length and file size to be 50MB, restarted clamd, and then my Transfer worked fine.
Your environment (version of Archivematica, OS version, etc) 1.7.2 on 16.04 LTS
