Hello,
Apologies for a second post. Our senior system admin just sent this to
me;
" The vsyscall for gettimeofday() was pointing to the wrong entry
address in RHEL4 U3. This was fixed as of U4. If the RHEL4.3 kernel is
used, vgettimeofday() will only result in dissapointment. Can you
upgrade to the RHEL4.4 kernel and re-test? I believe the problem has
been resolved."
Perhaps this may also be of use. I'm sorry I dont know the bug id
for that.
Andy
