Ok, I was able to create the packages with the debug info, adapted the script to report SIGTERM sent so any process, see attachment, tested this sending some SIGTERM and seeing them reported by systemtap.
Anyway, currently we are not able to reproduce the problem on the server, magically everything seems to work on this machine. The only changes should be the 2 debug-info packages (kernel-debuginfo-common-2.6.18-194.11.3.el5.x86_64.rpm and kernel-xen-debuginfo-2.6.18-194.11.3.el5.x86_64.rpm).
In the same time, the problem appeared twice today on our testing server. This suggests to drop the hardware failure hypothesis.
I'm running systemtap on the testing server now, too.
