Suddenly getting Max CPU Time Exceeded

(moderation:
Suddenly on 13th Dec I'm getting tasks aborting with "Max CPU Time Exceeded" using v6.05. Never happened before. This may or may not correspond to the day I installed the monthly Microsoft updates.
Could someone competent take a look at a few of these results and offer solution? I'm getting the same error with Rosetta tasks also.
Suddenly getting Max CPU Time Exceeded

Hi
You're getting Exit status -177 (0xffffffffffffff4f) error, which is explained:
In addition I'd check in Boinc Manager under processor usage and make sure cpu time is set to 100%
Thanks, but I'm already aware

Thanks, but I'm already aware of the kind of error I'm getting. I have plenty of disk space, plenty of memory, plenty of everything; made no setting changes ever other than cache size. The cpu setting has always been 100%. My question is more about why I would suddenly start getting this error when nothing has changed on my end other than a recent MS update.
My tasks appear to be running to normal completion (about 24 hours) but then I get cpu time exceeded. Makes no sense to me. The BOINC FAQ says a reboot and restart of BOINC usually fixes this error but the MS update required a reboot and restart. So where do I go from here? This is very odd to suddenly get this error after 3 years of running Einstein and Rosetta.
I did notice in one of the task's output a reference to ntdll.dll. Don't know what to make of that; maybe it's infected.
If the ntdll.dll. file is

If the ntdll.dll. file is corrupt, uninstalling Boinc, then restarting the pc, and reinstalling Boinc is one possible way to correct the problem.
If you're convinced it's a corrupt ntdll.dll file you could perform a repair installation of Windows XP and it will replace the ntdll.dll file
It could also be a bad memory module in your system, so testing your memory could identify if there's a problem.
Doesn't appear to just be an Einstein issue, since you're getting them at Rosetta too.
You have another problem.

You have another problem. It's not the maximum CPU time exceeded that is the problem, but all those tasks go out with a Breakpoint Encountered (0x80000003) error.
It's very doubtful that's a bad batch of work on two projects at the same time.
I never got a good answer from Rom as to what causes the breakpoint, while neither this or this entry in the Trac Wiki makes much sense to me.
So let me ask Rom when he comes online.
I did get an answer from Rom.

I did get an answer from Rom.
OK, with that said, there's a problem with the maximum CPU Time or Disk Space Exceeded messages. If it were a problem with the application or a bad batch of work, we'd ALL have these messages. I see others here crunch tasks you have problems with normally.
The same applies to a bad MS update. If there was any such thing, a lot more people would be having these sudden problems.
So that's not it.
I asked Rom to take a look at some of the dumps, he couldn't see anything wrong with it. Nothing pointing in the direction of keyboard/mouse injectors that could possibly break this.
Which leaves as possibilities:
1. Anti Virus software.
2. Malware software.
3. Corrupt science applications.
4. Corrupt BOINC.
Thanks Jord. I'm near

Thanks Jord. I'm near completion (I hope) of two other Einstein tasks so I'll wait and see what transpires. Then I'll run a disk and AV scan. Been using the same Norton Internet Security package for several months now, but NIS updates itself continuously so maybe something happened I don't know about. I just hate this kind of enigma. My motto is REBOOOOOOT, the panacea of ages (or is it ageless?)

That reminds me of this problem, where tasks error out when interrupted between finishing crunching and uploading.

Hmmmmm, do keep an eye out for strange things. Peek here at Seti to see how intrusive NIS is becoming.
I'd say, test other projects as well, see if they behave the same way.
RE: RE: Norton Internet

Thanks to those who responded. Einstein and Rosetta tasks are completing OK now. With the last MS update I failed to follow my own instincts. After MS updates I would notice that my system sometimes had mildly unusual and unpredictable behavior. Through experimentation I discovered that rebooting twice after an MS update would obviate post-update complications. I failed to reboot twice after the last MS update and paid for it I think.
As for Norton Internet Security, I have used it for several years without any issues. I do not exclude the BOINC folder or files in my scan and even run scans while BOINC is running; no problems. So I can't understand why other people seem to have problems with it. Maybe I skate by because I upgrade every year and have been doing so for several years. Maybe others encounter problems when installing NIS for the first time?
