how do I can strace process N1?
PaX doesn't kill bash if it executed not as process N1.

it's same on all servers:
# scanelf -lpqRte

Hmm. You think I should use PAGEEXEC instead? According to help in linux
kernel SEGMEXEC looks more suitable for Core2Duo and Xeon E5310...
In help for PAGEEXEC it doesn't recommended for P4 and there is nothing
about newest processors, so I suppose PAGEEXEC may not be a good choice.
After your question I've re-read help, and notice "i386 with hardware
non-executable bit support" item at end of list with less usual archs like
avr32, sparc, etc. If that was said about Core/Xeon too, then there
probably little usability issue with that help. ;-)
