Hi,

I am getting the following error when starting the application and refreshing the node:

My MongoDB version is 4.4.8.

Maybe the reason "memSizeMB" : NumberLong(772652) for this?

db.runCommand( { hostInfo: 1 } )
{
        "system" : {
                "currentTime" : ISODate("2021-10-01T10:51:54.950Z"),
                "hostname" : "core-hash01",
                "cpuAddrSize" : 64,
                "memSizeMB" : NumberLong(772652),
                "memLimitMB" : NumberLong(772652),
                "numCores" : 64,
                "cpuArch" : "x86_64",
                "numaEnabled" : false
        },

In ProfilingReader i made the following changes and the error disappeared:

hostInfoDto.setMemSizeMB(111);

Now I am getting the following error in other actions:
