To resolve the issue:

1. On the Apex One server, edit ofcscan.ini as follows:

   [Debug Log Setting]
   DebugFlags=0

2. On the Apex One web console, deploy the global setting to the agents through Agents > Global Agent Settings > Save.
3. On the agent side, check the registry value below:

   x64 machine
   [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TrendMicro\PC-cillinNTCorp\CurrentVersion\Debug Log Setting]
   "DebugFlags"=dword:00000000

   x86 machine
   [HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\Debug Log Setting]
   "DebugFlags"=dword:00000000

   If it does not match, try doing a manual update and then check again.

4. Reboot the machine.
