XMLWordPrintableJSON

    • Type: Icon: Bug Bug
    • Resolution: Fixed
    • Priority: Icon: Critical - P2 Critical - P2
    • 2.14.0
    • Affects Version/s: 2.13.2
    • Component/s: None
    • None

      Application info:
      TargetFramework: .NET 3.1
      Project type: Microsoft.NET.Sdk.Worker
      sqlConnectionString: "mongodb://ip1:3717,ip2:3717/admin?replicaSet=mgset-500180545&readPreference=secondaryPreferred&maxPoolSize=1000&wtimeoutMS=10000"

      my app will dead lock sometimes.I get the dump and analysis.I find that it will always happen after "MongoDB.Driver.Core.Misc.SemaphoreSlimSignalable.Signal()".
