I believe you experienced a 3rd possibility that other users are getting hit with is that cpu time is being reset to 0 and then counts up till workunit completes.

Also there is text in your stderr out:

-core_client_version>4.19-/core_client_version>
-stderr_txt>
boinc_init() v4.61
boinc_init() v4.61
boinc_init() v4.61
boinc_init() v4.61
boinc_init() v4.61
boinc_init() v4.61
boinc_init() v4.61
boinc_init() v4.61
boinc_finish(0)

-/stderr_txt>

Other users do not have this text.

I also have an example with a 1,000,000 turn boince workunit:

http://lhcathome.cern.ch/workunit.php?wuid=76170

One user reported with a time of 845.61 seconds and claimed credit of 1.28,
I had a time of 33,748.80 seconds and claimed credit of 99.67.
Granted credit was 1.28 :(

Interestingly this user also has linux os and stderr out text the same as yours.

Get a grip on yourself. I posted to confirm PeteHow was correct. And that there was not a spyware, virus issue or anything else involved. I can be sure because I used 2 programs to verify that it was LHC's application writing to disk. I never stated it was a problem.

@Ageless - don't dismiss someone's post so easily.

Currently I'm running a 100,000 turn wu. It's writing to 30 fort.xx files very frequently.

PeteHow is correct. The LHC application is writing to a large number of files in the slots directory very frequently.

The files are named fort.xx where xx is a number.
