DCT cost me some time today

On one of my servers I had very obediently appliead the following notes.ini parameter:

LOG_DISABLE_SESSION_INFO=1.

Today I found out that the Usage views in my server Log were empty. Comparing the 2 server docs and 2 configuration docs pointed at this variable that was only entered on that specific server (the busiest one ofcourse).

After setting it to zero and removing it, the views are filling up again nicely. So the advice of the day is: Be carefull with following the advice, it can do more than you initially think!

This is what the variable does:

---

Allowing 'LOG_DISABLE_SESSION_INFO' in NOTES.INI to remain absent will result in additional logging.

Explanation:
The LOG_DISABLE_SESSION_INFO setting when enabled, will turn off the writing of various session events to LOG.NSF.
DEFAULT: When absent or set to 0, various session events are logged and may decrease performance.
Configuration changes of this setting are automatically detected every 5 minutes.

Recommendations:
Consider enabling this setting with LOG_DISABLE_SESSION_INFO=1 to reduce logging and improve server performance.

I've now disabled this one in the configuration so I won't enable it again
