HELP!!!! I've been running E@H for many moons now without any hiccups. A few weeks ago, I noticed that E@H was not receiving any new work, while SETI was doing fine. I read a few posts on the boards that explained that my SETI project was trying to "catch up" with E@H. Sure enough, a couple of days ago E@H downloaded a new task. Now today, I was hit with the following;

26-Nov-07 04:28:55|Einstein@Home|Starting h1_0555.20_S5R2__103_S5R3a_0
26-Nov-07 04:29:06|Einstein@Home|[error] Process creation failed: The handle is invalid. (0x6)

And a bit later, I got this;
26-Nov-07 04:29:59|Einstein@Home|Sending scheduler request: To fetch work. Requesting 9394 seconds of work, reporting 1 completed tasks

And the worst part is this;

26-Nov-07 05:30:22|Einstein@Home|Sending scheduler request: To fetch work. Requesting 9482 seconds of work, reporting 1 completed tasks
26-Nov-07 05:30:27|Einstein@Home|Scheduler request succeeded: got 0 new tasks

26-Nov-07 05:30:27|Einstein@Home|Message from server: (reached daily quota of 2 results)

Any help received will be GREATLY appreciated.....

Error. The Handle is Invalid. (0x6)

Hi JC,

I'll deal with the last bit first. You have a daily limit of only two now because your machine has been trashing results for quite a while apparently. If you examine your results list you will see 21 consecutive compute errors with probably more that have now expired from the database. No doubt they are all exactly the same as the two you posted about. Your daily limit gets progressively reduced as your machine continues to error out the tasks sent to it.

What is causing this? I don't know, but we can make a few guesses about things to consider. Each errored result shows zero compute time so BOINC seems unable to even start the science app. The error message says that - Process creation failed. The reason given is "The handle is invalid".

When BOINC needs to start the science app, it needs to create a separate process and I imagine this is done by a call to a standard OS routine. Windows has such a routine called CreateProcess which returns "handles" (OS generated identification numbers) for the newly created child process. The error message says that the "handle is invalid" meaning that something went wrong during the creation of the child process that prevented a valid handle from being generated.

To my way of thinking, I would suspect that something else, like malware tools or anti-virus or firewall software for example, might be interfering. So the question to ask yourself is, "What other software have you installed or updated around the time that these problems first started. The time frame has to be on or before 18 Nov, which is the earliest date currently showing in your results list.

If you think there is nothing of this nature that could be doing it, a second course of action might be to see if starting afresh will fix things. As you have no current tasks on board, you could do a project reset for EAH which should get you new copies of data and executables. If that doesn't fix things, I'm not sure what to suggest next. You could completely detach from the project and clear out everything from the EAH project folder and then attach again. By doing this you would get a new computer ID but you should be able to merge both the new and the old IDs at a later stage.

Have a good hard think about any changes or updates you made to your computer a couple of weeks ago as a first step though. Good luck!

Cheers,
Gary.

Gary,
Thanks so much for your reply. I will take your advice and see what I can come up with. Ill let you know what happens.
Thanks again!

Gary,
I did actually add the program "Spyware Terminator" to my computer on Oct. 29, so, I looked around in the program and, sure enough, there among the list of blocked processes was a string for E@H. I went ahead and removed. I tried an update of E@H and then, did a project reset and here is the message that I received;

I dont understand why its telling me that I've reached this quota when nothing has been done in weeks.
Again, any assistance is very much appreciated.

If you have a look at your results list you will see that you have returned errored out results right up to Nov 29 and then more on Dec 05 and 06. Until you stop the spyware program interference which is apparently causing these errors you will be unable to increase your daily quota of 1 task per core. I don't know anything about this "Spyware Terminator" you mention but it sure seems likely that it could be the culprit.

As soon as you start returning valid results, your daily quota will automatically jump rapidly.

Cheers,
Gary.
