I suddenly get some performance counter exception

Aug 25, 2013 at 11:39 PM
I rebuilt my laptop from scratch, reinstalling Windows and everything else.

I had a working prototype of a custom protocol, but now I get an exception when I start supersocket.socketservice. This used to work before the laptop rebuild.

I get the same exception when trying to start CustomProtocol in the Quick Start samples.

I tried using disablePerformanceDataCollector on the root node, and that fixed the issue.

But what if I want to use the performance counters? Currently I cannot.

Here is what is in the error log produced by SuperSocket.SocketService:

Probably it s caused by local environment changes like anti-virus software installation or windows update?

You can fix it by run the command in the command prompt to rebuild the performance counter index:

"Lodctr /r"

This fixed my issue. Thanks!

I am very happy with your code. You have saved me a lot of work on a project with which I am involved.

I am glad to hear that!
