Sysmon 8.04 memory leakage problem

    Question

  • Hello,

    We are facing memory leakage problem with newest version of Sysmon (v8.04) on hosts with MSSQL installed.
    On servers with such problem we ran powershell script which collect every hour information about memory used by sysmon. After one week we can see that memory used by sysmon grows up in linear way. We faced such problems in previous version, and still have same problem. The only way to release the used memory is to restart the service.

    Below information about software installed on one of "problematic" host:
    Windows Server 2012 R2

    Microsoft SQL Server Management Studio 11.0.7462.6
    Microsoft Analysis Services Client Tools 1.0.7462.6
    Microsoft Data Access Components (MDAC) 6.1.7601.17514
    Microsoft MSXML 3.0 6.0 
    Microsoft Internet Explorer 9.11.9600.19236
    Microsoft .NET Framework 4.0.30319.42000
    Operating System 6.1.7601

    Graph of memory usage over time:

    As you can see in 12 days, memory usage gradually increased in a linear way.

    Have anyone faced same problem or maybe it has already been reported and will be addressed in next release?
