Domino version 9.0.1FP5 HF71
Windows version 2008 R2 Ent SP1
Memory 16GB
CPU 4 x 2.30GHz
Virtual
Memory usage is very large on the server and I tried to use “drop all” from Domino console. I then receive the message
“Maximum number of in-memory log entries exceeded; cannot create another until some are flushed to the log database”
After a couple of “dbcache flush” commands I reduce the memory usage with about 10-15% but it is still high and the message keeps appearing after I try to use “drop all”.
I do not want to restart the server since it is a mailserver.
Subject: What’s the % disk usage on the log.nsf?
Lower values of %used on the log.nsf means, it’ll take longer to flush log entries to the log.nsf. And yes, it requires a server restart. But you can prep a new log.nsf (copy the old log.nsf then do a quick renaming while the server’s down), so your server is not down while you’re messing with it.
What’s your server_session_timeout value? Don’t leave it at the default.
If your users are polling too quickly for new mail this’ll use up memory as well. Users should use a practical value for this check: it’s mail, not instant messaging.
Subject: Try…
Try increasing the size part of the notes.ini setting LOG.
e.g. from LOG=log.nsf, 1, 0, 7,30000 to LOG=log.nsf, 1, 0, 7,50000
Will need a restart though.
Subject: Some changes
Thank you for your replies.
I’ve changed the following
Log=log.nsf, 1, 0, 7, 50000
Server_Session_Timeout=30
We have a policy already in place to let users check their mails every 10 minutes.
Also I brought down the server and moved log.nsf (28% usage) to a backup location. Server creates a new one automatically.
Will let you know if this helped or not.
Subject: Still same issue
Sorry no luck! Still the same problem. Log at 95.5%.
Subject: Event logging
It could be that your server is logging too much or that the event pool is not large enough.

Have you tried to reduce the volume of logging, do you have any debug running?
Stop logging sessions: Log_Sessions=0 (notes.ini)
Reduce router noise: Router/SMTP → Advanced… → Logging Lever: Minimal (In the config document)
As it’s a virtual box, check the average disk queue length on the Domino data drive the disk could be below par for Domino.
Edit: You can also try LOG_DISABLE_SESSION_INFO = 1 (https://www-10.lotus.com/ldd/dominowiki.nsf/dx/log_disable_session_info-disables-the-logging-of-various-session-events https://www-10.lotus.com/ldd/dominowiki.nsf/dx/log_disable_session_info-disables-the-logging-of-various-session-events)
