Environment

  • Liferay SaaS / PaaS and clamAV antivirus enabled.

Resolution

  • PaaS
    • You could disable clamAV itnegration temporary.
    • As an alternative, clamAV limits could be raised by modifying clamd.conf but it impact the performance of your server, and should not be higher than 2GB. 
      • MaxScanSize 1000M
MaxFileSize 1000M
StreamMaxLength 1000M
  • SaaS
    • This limitation is currently a feature of the SaaS model and cannot be disabled by default, so each case will be evaluated and resolved individually.
    • Contact Liferay through a support ticket for assistance.
