Hi all, I am working with two MIPS based boards (one is MIPS and the other is MIPSEL) running linux-2.6.18/glibc-2.3.5. I am performing a consecutive reboot test on these boards. After some number of reboots (say 80) I am getting "segmentaion fault/illegal instruction" while running udevd and ntpd during bootup. Upon observing the core dump, it is noted that the segfault occured from the _init function of libnss_dns.so (in the case of ntpd) and libnss_compat.so (in the case of udevd). I assume that there might be a problem somewhere in the call_init function in glibc-2.3.5/elf/dl-init.c. After I put some printf statements for debugging in the call_init function, there is no segfault/illegal instruction in the reboot testing. I have also used gdb to debug the problem but the "segfault/illegal instruction" doesn't occur during the reboot test. Could anyone please help me to sort out this problem. The gdb output using coredump is attached. Any help will be appreciated Firos -------------------------GDB O/P--------------------- -bash-3.00# gdb -c core udevd GNU gdb 6.2.1 Copyright 2004 Free Software Foundation, Inc.
