This happens to me once in awhile. I am running a 2.26 Pentium 4 with XP. I would turn on my computer more, but the electricity bill would not get paid. LoL

the recent BOINC Clients (beginning with V4.45 I think) take into account the time your computer is turned on!
In the quote above the computer is turned on 'only' 17% of the time. BOINC client calculates the estimated duration multiplied with 'turn on time'. If this time is beyond the report deadline the computer will not get any more work (-> computer is overcommitted)!
2) Message boards : Number crunching : Strange WU 509911 (Message 9840)

By chance I noticed this strange WU:
http://lhcathome.cern.ch/workunit.php?wuid=509911
Computer 47120 claimed only 4.61 credits and has error messages:
-------------------
boinc_init() 4.65
No heartbeat from core client for 30.059123 sec - exiting
boinc_init() 4.65
boinc_finish(0)
-------------------
As far as I know, exiting the computation process after aprox. 10000 CPU secs (where the other computers took much more) should not lead to a valid result.
3) Message boards : Number crunching : Running 2 WU's simultaneously with one processor after benchmark.. (Message 8735)

This is the 'normal' behaviour if you have more than one project.
At Switch time all activity is suspended and the next project gets the processor.
If you have 'even weighted' projects (i.e. each project with '100') then Boinc will switch the projects every hour.
