Disable Auto Refresh Delegate inbox

Daniel Nashed  December 9 2020 10:58:42 PM

When you open multiple other mail databases -- for test, production administration, the client will keep track that you opened the database and will poll the delivery sequence number permanently.
This is intended for new mail notifications in delegate mail databases.
But this is often not desirable and causes CPU overhead as my friends from Panagenda reported in detail a while ago --> https://www.panagenda.com/2019/01/why-your-domino-servers-might-have-been-using-30-more-cpu-recently-and-how-to-fix-it/

I just ran into it again today with 11.0.1 FP2 on my machine with a very high latency to an US server.
You usually don't see those transactions unless your client runs with client_clock=1 and debug_console=1  (see below)

There is a parameter that isn't well documented. It has the prefix DEBUG. So this is more a work-around..

notes.ini DEBUG_DISABLE_AUTO_REFRESH_DELEGATED_INBOX=1 (This is a per client setting to disable the functionality)

The feature has been introduced in 9.0.1 FP9. You find detail in the following technote -> https://support.hcltechsw.com/csm?id=kb_article&sysparm_article=KB0040095
