Domino 8.5.2 64b memory leak?

HCL Domino Domino Forum

We upgraded one of our Domino Servers from 8.5.1 FP1 to 8.5.2 (both 64bits).

Server => Virtual Server on VMWare ESX 4.0

Guest machine =>Quadcore+ 4GB RAM + Windows2008 R2

On the very beginning we saw that the dominos processes (nserver, nupdate, nhttp, nadminp, nrouter,…) began to take memory and after some days, the server showed a 90% of memory utilization and it remained constantly with such a big memory utilization.

The strange thing is that apparently everything is working correctly, so the users are not complaining about slow response time or other problems.

After talking to IBM we tunned it with some parameters and now the standard memory utilization is about 70%.

Before we go further updating the rest of the domino servers I woud like to be sure if this is normal.

Does anybody knows if this high memory utlization is normal?

Thanks in advance,

Ricard Malvesi

Subject: 64 bit shared memory space

Just a short question: is the Domino server also 64bit or did you use the 32 bit version on the 64 bit OS? In my experience the OS hands over a larger chunk of memory that Domino can now address as shared memory and that will lead to higher memory utilization over time. Do you use any other Domino add-in tasks that are not part of the Domino stack (AV, etc.)?

Hi Ricard,please could you explain what are the parameters tha IBM suggested that allowed you to limit the memory leak ?

Thanks
