LHC@home

I had this problem a few times.

I have a P4-2.6GHz with HT that is 2 logical CPUs.

I have 3 attached projects now - CPDN, S@H and LHC. There are 4 S@H & 8 LHC@H WUs with "Ready to report" status and 1 CPDN WU currently running. I can not report finished WUs because S@H scheduler always not responded and now LHC scheduler also (Too many connections message some times)

When BOINC finished last LHC WU then BOINC hangs (I could not change BOINC pages and so on). Then I closed BOINC with Task Manager. After that I changed Global prefs from Max 2 CPUs to 1 CPU and restarted BOINC. And now it works (with CPDN WU).

This problem happened earlier when S@H Wus were finished. After that bug previous CPDN WU (with ~40 percent) was lost :(

This problem happened with BOINC 4.09 but 4.05 has not this problem (it seems).

Sorry for my terrible English :( I hope you can understand me and my problem.

You have 2 CPU's and BOINC wants both of them to do work. However, it seems in your situation that only one CPU can be used for a WU, but both CPUs must be used! This is not possible, so the program crashes. This can be solved simply by caching a lot of work. Go to preferences and set contact server time to a reasonable amount(i have machines that must connect to the internet with human intervention) , so i use a 5-day queue.
