[Jerwin Roy]

Hi guys,

When i run db.currentOp(true) i am getting the below output with op:none,empty ns & query.Can anyone provide me the solution?

{
    "opid" : 2741774,
    "active" : true,
    "secs_running" : 65690,
    "microsecs_running" : NumberLong("65690930015"),
    "op" : "none",
    "ns" : "",
    "query" : {
       
    },
    "desc" : "repl writer worker 1",
    "threadId" : "0x7ff4a5cd3700",
    "waitingForLock" : false,
    "numYields" : 0,
    "lockStats" : {
        "timeLockedMicros" : {
            "r" : NumberLong(0),
            "w" : NumberLong(103)
        },
        "timeAcquiringMicros" : {
           
        }
    }
}

Hi Jerwin,

The output of db.currentOp(true) includes system operations and idle connections, so it is expected that you will find some threads that aren't associated with a specific namespace or query. The information on system operations and internal threads generally isn't meant for end users to interpret or action (eg. definitely don't kill unknown system operations!).

The description of the operation you have noted is "repl writer worker" thread, so this output is presumably from a replica set member which will have multiple worker threads present:

    "desc" : "repl writer worker 1",

Regards,

Stephen
