confused [RESOLVED] Can't acquire lockfile - exiting
Hello,

I have a problem with one of my computers. When new WU starts it errors out with this message:

<core_client_version>6.2.28</core_client_version>
<![CDATA[
<message>
too many exit(0)s
</message>
<stderr_txt>
Failed to get VersionInfo size: 1812
Can't acquire lockfile - exiting
FILE_LOCK::unlock(): close failed.: No error
Bold text is present maybe 30 times.

When I watch it and restart computer before WU errors out WU normally starts. This happens on FLU WUs cos computer is crunching only FLU. But I assume this would happen on all projects.
OS: WinXP, Firewall: NOD4. Boinc is clearly installed on computer (new notebook DELL) and is running under restricted account.
I found some info on web but didnt help.

Re: Can't acquire lockfile - exiting
Very probably you have a security problem through NOD4. You need to exclude the BOINC data directory, see you client message log for location, from scanning. It's a sand boxed area, so there is no risk doing that. Security software does not like BOINC communications and frequent disk writing.

Too many exits

Is NOD4 in learn mode? It should pop up a request to permit the BOINC and WCG processes you see in the taskmanager, temporary or permanent. Instead it is probably just silently blocking.

NOD was my guess also. It is not in learning mode. But I cant find a firewall log to see what the problem is. I tried it first. However I try to put it to learn mode and/or exclude BOINC directory from scanning. Thanks Sek.

Yeah I know smile
But as I see now it is an intermittent problem. Some WUs starts normally some doesnt. So I am a little bit confused. No matter, I try to resolve it somehow. smile

Thanks for help.

Re: Can't acquire lockfile - exiting
Are you saying some FLU jobs just pass without the issue? Heuristic functions in security software are nice and a pain. It could be seeing patterns it 'guesses' are not right and blocks a transaction. BUT, lock file hints at a conflict. The science software wants to write and NOD4 grabs it to do a scan.

Yes. Some jobs are pass w/o this issue. Should I turn off heuristics?

OK. I am not near the notebook now. But I try it and reply whether I succeed or not. (And probably I need to wait for another WU to start either. smile )

Thks.

Re: Can't acquire lockfile - exiting
Sek it looks pretty good (after BDD excluding). First WU (after excluding) started normally. Waiting for the second. (dual core smile )

Edit: Second WU also strarted normally so it seems to be resolved.

Thanks for help.
