Hi,
I am Basant Kukreja. I was working on apache httpd bug 42580.
http://issues.apache.org/bugzilla/show_bug.cgi?id=42580
I figured out that the cause of the problem might be in APR.
apr_pollset_poll function returns APR_TIMEUP even when errno is EINTR. The
caller functions e.g listener_thread (in worker.c) expects this API to return
APR_EINTR if apr_pollset_poll fails.
Other implementation of apr_pollset_poll (as in epoll.c) handles it correctly.
Please provide your comments. Suggested patch is attached. With this patch the
issue 42580 seems to be fixed to me.
Regards,
Basant.
