A memory leak on Windows Server 2008 R2 #22

Open maraev opened 8 years ago

maraev commented 8 years ago

Hello, First of all, thanx for your good application. It works fine on my Win7 system. Second, I've tested it on my Win Server 2008 and watching that the operation memory was filled during some days. carbonator1 How can I fix it?

test-in-prod commented 8 years ago

Do you know which build of Carbonator you are running?

  1. Download and unpack CLR profiler
  2. Run CLR profiler (Binaries\64\CLRProfiler.exe)
  3. Attach to process (enter PID of the Carbonator process)
  4. Click "Show Heap Now"
  5. Expand the heap window and try to take a screenshot (play with Scale/Detail radio buttons)
  6. Post screenshot here
  7. [Heap Graph Window] -> Edit -> Copy as text to clipboard
  8. Paste that text here

Thanks!

Hello! Unfortunattelly, I'm not expert in CLR Profiler debuging. I've stuck on step 3 with getting message form CLRProfiler like er1 Event 1022 .Net Runtime .NET Runtime version 4.0.30319.1026 - Loading profiler failed. The profiler COM object was instantiated, but the profiler failed during its initialization callback. Profiler CLSID: '{8C29BC4E-1F57-461A-9B51-1200C32E6F1F}'. HRESULT: 0x80131376. Process ID (decimal): 1184. Message ID: [0x2505]. Also just to clarify I'm getting error log when I try to start the service Carbonator v.2.0 

Service cannot be started. System.Configuration.ConfigurationErrorsException: Unrecognized attribute 'logLevel'. Note that attribute names are case-sensitive. (C:\Program Files\Carbonator\Crypton.Carbonator.exe.Config line 13)
   at System.Configuration.BaseConfigurationRecord.EvaluateOne(String[] keys, SectionInput input, Boolean isTrusted, FactoryRecord factoryRecord, SectionRecord sectionRecord, Object parentResult)
   at System.Configuration.BaseConfigurationRecord.Evaluate(FactoryRecord factoryRecord, SectionRecord sectionRecord, Object parentResult, Boolean getLkg, Boolean getRuntimeObject, Object& result, Object& resultRuntimeObject)
   at System.Configuration.BaseConfigurationRecord.GetSectionRecursive(String configKey, Boolean getLkg, Boolean checkPermission, Boolean getRuntimeObject, Boolean requestIsHere, Object& result, Object& resultRuntimeObject)
   at System.Configuration.BaseConfigurationRecord.GetSectionRecursive(String configKey, Boolean getLkg, Boolean checkPermission, Boolean getRuntimeObject, Boolean request...

therefore I'm testing on v.1.5

test-in-prod commented 7 years ago

Try turning off concurrent GC (step 1 in message box). You will have to restart Carbonator for this to take effect.

Version 2.0 was recently updated, try the latest build. As for configuration errors you are seeing in that, note that 'logLevel' is deprecated setting and needs to be removed from your config.

Hi! I'm not sure about accuracy the following screen but still carbmemleak I haven't done attach PID number, just run as a Profile Service I'm still have the issues with carbonator 2.0. Despite I've fixed some lines in config file, service haven't started. So I've tested on v.1.5 Please see my config as well
