Re: [Condor-users] Performance Counter Error


Hi TJ,

Thanks! I will try to findout if there is a virus.
If it happens again, I will return to you.

Regards,
Klaus

Re: [Condor-users] Performance Counter Error





There is no way to avoid the error, because it shouldn't be happening in the first  place.  

The code is calling ReqQueryValueEx(HKEY_PERFORMANCE_DATA, PERF_PROCESS_LIST ),  the function is returning success, but the data appears to be partly invalid - it has the correct starting bytes, but there is a 0 in the field that shows the size of one of the counters. (the first one that we check)

The message that you  are seeing is there just so that if some future version of Windows changes the structure of the performance data in a way that violates some assumption in the code, we get a message rather than a random crash.    The code is checking to see if sizeof(perf_counter) == 8 on the current platform.  If this fails, I would expect it to fail all of the time on a given version of Windows.

Please let us know if you see this happen again, but I think it's very unlikely that its a bug in the Condor code and very very unlikely that it's a configuration problem.   It might be a bad DIMM, or a Windows bug, but I still think that you should check for a rootkit type virus - a virus attempting to edit itself out of the process list might cause this symptom.

TJ,

The second explanation (virus) is an unlikely possibility because our company installs an antivirus software in all desktops but could happen if the virus definition does not have its definition yet.

Is there any way to avoid this error? We do not have many Windows 7 machines yet, but it will be a problem when more win7 desktops will be deployed in the company and an end user, that does not have rights to start the Condor service, needs to run jobs.

Thanks,
Klaus

Re: [Condor-users] Performance Counter Error







There's nothing much you can do about this unfortunately.   This is a truly bizarre thing to be intermittent.
The message is a bit misleading, you are not expected to have a key at that point in the registry.  Its just
that if you DO have a key there, it's value should be 0.

There's a Windows API  that we query that returns a structure and another API that returns some information
describing the format of that structure.  That second API is returning unexpected values for the formatting
information.

The thing is, that formatting information isn't allowed to change at runtime.  In practice it changes between
versions of Windows, but doesn't change within a version.   So the error you are seeing simply CANT be
intermittent.  

I can think of only 2 possible explanations.

1)  Something in Condor_master is randomly overwriting memory and it happened to hit this formatting
information - unlikely.

2) You have a virus that is trying to hide itself and the code isn't quite right.

HI,

When Condor started this morning on my Win 7 Desktop, it aborted and logged the following error message in the MasterLog file:

There isn´t an entry Disable Performance Counters in this registry path.

I am using version

C:\Users\kschwarz>condor_version
$CondorVersion: 7.6.0 Apr 16 2011 BuildID: 327460 $
$CondorPlatform: x86_winnt_5.1 $

C:\Users\kschwarz>

Trying to start it again, the error disappeared and Condor is running well.

What should I do to prevent this to happening again?

Thanks,
Klaus
