I read the earlier thread on signal 11 (may 2010) and understand that, but
it does not seem to be my problem.

I rarely see this, but today it came in a bunch. About the time I was
closing down a VMware session (several virtual machines).
Boinc is running native, not in a VM. Ubuntu 10.10 64bit. 12 cores.
(linux reports 24 cpus, but that is normal when hyperthreading
is turned on in the BIOS).

Notice that Einstein (also always running) never hits a Signal 11.

A dense listing of today's signal 11:

I just turned on core file recording (putting them
in /tmp/corefiles using /proc/sys/kernel/core_pattern) in case having
corefiles will help at some point.

One time I had a problem like this I booted-into the memory-tester
and ran memory tests 8 hours but no errors showed up.

I generate almost exclusively good results. So it distresses to
generate errors.
Suggestions?

More failures at 19:01 UTC Apr 25. No core files. Darn. The boinc
user is not getting ulimit -c unlimited set. No messages
in boincmgr about this.

No records in /var/log (linux log files). Nor in /var/lib/boinc-client
or its subdirectories (boinc logs are there) of failures or the tasks.
Aside from rare older instances of Signal 15. That I can find.

Try running the Optimised Linux apps, Arkayn has some combined packages made up on his site, just choose what flavour of SSE you require, and whether 32bit or 64bit,
