high CPU usage

<< < (4/4)

modisanyi:
Bingo!
With NOOP enabled, there is no high cpu usage.
But IMHO, there is something fishy with the ftp module (why does the cpu usage remain  - checked with processexplorer - even if I disconnect from the server - with noop disabled? ).

Thank you!

You say that there is no high cpu usage with NOOP enabled and then that cpu usage remain.. ?
Was the CPU issue solved with enabled AntiIdle. ???

I think it is because of a timing issue. The antiIdle handling (background work) gets into a state where it tries to get a connection (to do NOOP on), but it does not finds one but it continues to try to find one. over and over and over again.. (Just what I suspect.. Have not had time to check the code yet)

modisanyi:
Sorry, I mixed them up a little bit.

The cpu usage is solved with NOOP checked.

What I wanted to say, is that when NOOP is NOT checked, and I connect then disconnect from the server, the cpu usage will remain until I restart MC. I expected that when I hit disconnect, the ftp module to shut down.

As you said, the problem is caused most likely by a timing issue.

Thank you for your help!

Great.

The AntiIdle thread is running in the background and since it got into a loop checking for a valid connection is think it does not close that thread.. That thread just continues..  I will fix that for the next version.
