Hi. The problem is related to the resources on the Domino server.
The documentation states that it is necessary to use the value SWAP = RAM * 2. How important is this information? Is it possible to use a server with less swap space or no swap at all? What are the risks of disabling swap?
Domino 12.0.2FP6
Verse 3.2.4
OS RHEL 9
Hi.
This comes back from when physical servers and memory was expensive, so, servers usually had few memory.
In a server with 2 GB or less RAM, processes need to work with large memory pages, so, SWAP came to play.
Nowadays, with servers with 16, 24 or even hundreds of Gigs of RAM, SWAP may not be used at all.
If your RHEL setup has enough memory RAM (64+), more than the minimal required, considering your application (Domino) plus OS itself plus others apps may be running alongside your box (considering anti-malware, EDR/XDR, etc.), SWAP may not be needed.
In the case of RHEL, if you have KDUMP enabled, this may use SWAP, depending on your KDUMP settings. SWAP may come handy in case memory exhaustion for other processes.

Thank you. Did I understand correctly that SWAP is not required for Domino at all?
Applications usually don’t work with SWAP directly. Applications requests memory to the Operating System.
When the Operating Systems finds that there is no more available RAM, operating system may satisfy the request by means of providing the required memory from SWAP.

It turns out that SWAP is not a requirement with a large amount of RAM. Thank you. It would be great to include this in the documentation.
