Hi. A question about the memory used.
In server stats I see Allocated > 80GB but the server has only 64 RAM + 8 SWAP. How is it possible?

Here’s an example:
Mem.Allocated = 9,4065972062E+10

On the screenshot we can see that the swap is only 8 GB.
The question arises, where such a large amount of memory is allocated from: 89708?

PS: Domino is 12.0.2FP6.

Hello Alexsandr,

There is an issue with tracking memory allocations and deallocations. If a server has been running for an extended period, memory usage may exceed expected limits, reaching a value as high as 1.8446744073E+19.

When memory allocation surpasses this large number—exceeding what can be represented in gigabytes.

This issue has been reported under SPR# YCHACUZ9UH and has been deferred for a fix.

As a temporary workaround, restarting Domino is recommended.

If you want to further investigate this I highly recommend to create case for this issue.
