Noticed that Notes server is using most of the swap file when there is abundant available memory. Any ideas why this is happening?
Subject: Linux Swap File Use
Domino spawns a lot of tasks when launched, and many of them can be rarely executed, depending on the use you give to the server. Maybe some other program was run on the computer after Domino* (using the now available memory) and sent part of it to swap? If whatever code is in swap is not used, I doubt it will go back to memory until it’s needed.
*Or some other Domino tasks used the memory and freed it afterwards.

Domino does not use swap space specifically. All we do is ask for memory from the OS. We use both System V shared memory and malloc/calloc/free for our memory. So, if you are seeing the OS memory not getting used and everything going to swap instead then it would have to be something with the OS itself - something with the configuration, such as the kernel which was previously mentioned in a response.

Are you sure it is using swap space? (Had to ask sometime people misread that output of top)
Are you sure you are using a kernel which enable HIGHMEM? At times people have thought they were using all the memory in their server (over a GB), but the kernel was not recognizing any memory after the first 720MB.
I don’t think Domino is written in such a which to tell what processes will run under what type of memory (physical vs swap).
HTH cheers

My domino admin said it is using swap while only using about 300mb of main memory. Machine has a gig (or more). I’ll forward your response to him, maybe he missed something in setup. Thanks
