Hi All
In Notes log database lots of following entries have started appearing:
“4/04/2003 12:48:27 Monitor Error in Database C:\Lotus\Domino\Data\mail\dbname.nsf: Insufficient memory - NSF monitor pool event space is full.”
where dbname is the name of databases.
What does this error mean, is it serious and how can this be fixed?
TIA

Has anyone been able to find a solution to this problem? I have turned off headline monitoring and am still receiving these warnings. Thanks for any help.

Subject: I’ve noticed it happens when a new document is saved.
It can be a mail message that’s being delivered, or a new document in an application. But it always happens when either one of these two actions happens in one of the affected databases. I can produce this error at will now. But I haven’t solved it yet

I never saw the error “Insufficient memory - NSF pool…” until I upgraded our Notes servers to 6.02 CF1. I had been searching this forum as well as others, but no luck. I was talking to the developer about it and he found a Google forum that suggested we look at the following setting in the notes.ini file:NSF_FOLDER_POOL_SIZE_MB=2000 (Specifies the maximum size (in bytes) of the NSF buffer pool, a section of memory dedicated to buffering I/O transfers between Domino and disk storage. The maximum size depends on any limitations of the operating system, and the amount of system memory available. The minimum size is 4MB).
I haven’t seen the error since I increased the NSF buffer pool to 2000 - I think it was set at 1000.
PS Here’s a website we reference on any notes.ini settings…http://www-12.lotus.com/ldd/doc/domino_notes/Rnext/help6_admin.nsf/f4b82fbb75e942a6852566ac0037f284/92d75ed4dc4056ac85256c1d003a09f3?OpenDocument
I’m not sure if this setting will help everyone, but it helped us.

There is no Notes.ini setting titled NSF_FOLDER_POOL_SIZE_MB, the correct line I believe should be NSF_Buffer_Pool_Size OR NSF_Buffer_Pool_Size_MB.
This is from the Help Docs:
On the server, the default maximum is determined to be between 1/8 and 3/8 of available physical memory, depending on the overall size of physical memory. The defaults are not automatically adjusted on partitioned servers, so it will usually be necessary to adjust the maximum values in each partition to a fraction of memory such that the memory used by all partitions adds up to approximately 1/4 to 3/8 of memory.
Subject: Beware…
…setting the NSF_BUFFER_POOL_SIZE to 2GB can have serious side effects. I’ve seen servers become very unstable, by using this setting. You may want to use PercentAvailSysResources= instead. Or, in any case, read up on the subject before using either one parameter.

We’ve recently started seeing this error on our Domino 6.5.5 FP2 server. We cannot attribute it to any system change.
Monitor Error in Database d:\notes\data\names.nsf: Insufficient memory - NSF monitor pool event space is full.
I have tried disabling Healdline Monitoring on the database, but that doesn’t seem to have any impact. Interestingly this error seems to occur only between 10:34pm and 8:57am.

You are not alone…I’ve been having the same issue since my upgrade to ND6 , but only on one database. I’m now running 6.01CF, and it’s still not fixed. I’ve found that the messages stop when I disable one of the agents in the database which modifies the documents. One of the original developers thinks that it might somehow be related to subscriptions on the DB… Any help would be appreciated. Thank you

Hi There,
I also have this big problem. On my server it appears on 3 different databases, always mail databases.
And it’s not on a regular basis… I mean it doesn’t appear always at the same time or same hour… (and this doesn’t appear more than 5-6 times per day)
Help would be greatly appreciated because our domino server, based on linux, crashed yesterday.
Regards,
Subject: Disable headline monitoring?
Like Paul said, it could have something to do with headline monitoring. Have you checked with the owners of these mailfiles if they use headline monitoring for their mailfile? What happens when you disable headline monitoring? You can do that in the database properties, advanced options (last tab), ‘don’t allow headline monitoring’.

Has anyone been able to find a solution to this problem? I have turned off headline monitoring and am still receiving these warnings. Thanks for any help.
