VirusScan during upload failed for pdf file 37 MB

[dimipapadeas]

During an attempt to upload a pdf file (37 MB size), it seems that the virusScan failed with no error message.

We saw that the failure was in io.sensesecure.clamav4j.ClamAV class at
scan(InputStream inputStream, InetSocketAddress address, int timeout) method.
