Shortly after upgrading to ProxyAV OS 22.214.171.124 on the AV2400, some hardware components such as CPU temperature, CPU voltage are reporting 0s or critical. Although the appliance health is in a critical state, it continues to process and scan traffic.
Update: We have confirmed that this issue affects AV1200s, AV1400s and AV2400s. Also and type of reboot of the AV (after upgrading, manual reboot or crash) can possibly trigger this issue.
Bug 148440 and 188897 have been opened to investigate this issue. The current fix for this issue is to do a soft reboot (found in the Utilities section of the management console) on the ProxyAV.
