Created attachment 513952 [details]
strace output while X got segfault (See line 70-80. )
This symptom can be reproduced on bare metal system, as well as RHEL5 running on VMware Player. Created attachment 513979 [details]
Capture segfault using gdb
Run X on gdb and try to capture the backtrace of the point
where segfault happen.
I have installed glibc-debuginfo and xorg-x11-server debuginfo RPMs.
Additional information. When this symptom happen, following messages are logged in /var/log/messages. rhel5 kdm: :0[14741]: Hung in XOpenDisplay(:0), aborting rhel5 kdm: :0[14741]: Cannot connect to :0, giving up rhel5 kdm[8167]: Display :0 cannot be opened Created attachment 514146 [details]
Capture segfault using gdb with all debuginfo RPMS
Same test on RHEL5.7(64bit), the same symptom still exist.
The backtrace of the X process segfault.

similar backtrace, (hit segfault free => malloc_consolidate).
http://people.redhat.com/tumeya/.sf00518164_x_hang/ Masanari, I haven't been able to reproduce this. While trying this, is it possible for you to try the test packages above? Thank you for your cooperation. Umeya-san Thanks for update. I have downloaded the RPMs and started to test. I will provide the feed back of the logout/login test result on early next week. *** This bug has been marked as a duplicate of bug 674741 *** |
