Hi Lee, Does the kernel that you are running support NPTL threads at all? I recall that using LinuxThreads on Opteron x86_64 is strongly discouraged .. Alternatively, maybe NPTL is the problem on outdated 2.4 kernels.. does the RHEL3 update include the futex bug fix reported here http://www.uwsg.iu.edu/hypermail/linux/kernel/0409.0/2044.html I am shooting arrows in the dark here :) Thanks, Murali
