Description Konstantin Olchanski 2003-03-23 23:05:36 EST

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3) Gecko/20030301

Description of problem:
"ps", "top" and others hang on reads from /proc/PID/stat. The hung processes
cannot be killed and the system eventually becomes unusable and has to be reset.

This hung happens rarely, less than 1 per month per 20 systems. I have seen it
with kernels older than 2.4.18-19.8.0, never with vanilla 2.4.20 and (never?)
with redhat-7.x systems. I will be updating the currently hung system to
kernel-smp-2.4.18-27.8.0.athlon.rpm and will report if the hang reappears.

I am attaching the output of "strace ps -ef" and "alt-sysrq-t". Note that "ps"
is hung on a read() from "/proc/30731/stat" and the kernel stack trace shows it
waiting on a lock inside sys_read()->proc_info_read()->alloc_inide(). Please let
me know if you need any additional information from the hung systems.

Comment 3 Konstantin Olchanski 2003-04-11 00:19:00 EDT

Okey, I see the same problem on a redhat 7.3 system with the 2.4.18-24.7.xsmp
kernel. The symptoms are slightly different- userland still hangs on reads from
/proc/PID/stat, but the alt-sysqr-t output now show them hanging in
sys_read->proc_info_read->__alloc_pages->.text.lock.array: (full trace available
on request)
