           Summary: on major load on the server, poll() hangs
           Product: Apache httpd-2
           Version: 2.2.16
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: worker
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: tal.yalon@gmail.com


Hi there,

Thought this bug is related to bug #50247, but as per Eric's suggestion I'm
opening a new bug.

The httpd in question is 2.2.16 running on EC2.

We see that after ~10 minutes of significant load, some of the worker processes
get hang on poll().

By hang I mean that poll() call didn't finish for more than 30 seconds.

This is the stacktrace from one of the processes that are in this state:

#0  0x00007f76fa70c748 in poll () from /lib64/libc.so.6
#1  0x00007f76fabe2822 in apr_wait_for_io_or_timeout () from
/usr/lib64/libapr-1.so.0
#2  0x00007f76fabdd2da in apr_socket_recv () from /usr/lib64/libapr-1.so.0
#3  0x00007f76fc0dfddd in ap_lingering_close ()
#4  0x00007f76fc0eaa7e in ?? ()
#5  0x00007f76fc0ead1a in ?? ()
#6  0x00007f76fc0eadd0 in ?? ()
#7  0x00007f76fc0eb908 in ap_mpm_run ()
#8  0x00007f76fc0c54fb in main ()

Please let me know if there's any more information I can provide - this problem
is obviously a major concern to us.

Thanks,
Tal
