configure hangs after checking whether SCTP is supported

I'm trying to install the Apache httpd server on a Red Hat Enterprise
Linux Server release 5.1 (Tikanga). The output of uname -a is:
Linux server_name 2.6.18-53.1.19.el5 #1 SMP Tue Apr 22 03:01:10 EDT 2008
x86_64 x86_64 x86_64 GNU/Linux.

I get the same results for both 2.2.4 and 2.2.8. Basically, in the
/opt/httpd-2.2.8 directory I run
./configure --prefix=/opt/apache2.2.8 --with-included-apr
or
./configure --prefix=/opt/apache2.2.8.

In both cases configure hangs after echoing " checking whether SCTP is
supported...". The process never dies and does not respond to control-c.

The last several lines of output are:
Checking for Networking support...
checking for in_addr in netinet/in.h... yes
checking if fd == socket on this platform... yes
checking style of gethostbyname_r routine... glibc2
checking 3rd argument to the gethostbyname_r routines... char
checking if TCP_NODELAY setting is inherited from listening sockets... yes
checking if O_NONBLOCK setting is inherited from listening sockets... no
checking whether TCP_NODELAY and TCP_CORK can both be enabled... yes
checking for TCP_CORK in netinet/tcp.h... yes
checking for TCP_NOPUSH in netinet/tcp.h... no
checking for SO_ACCEPTFILTER in sys/socket.h... no
checking whether SCTP is supported...

I googled both sctp and 'configure hangs' but did not see any suggestions
on how to resolve the problem. Since this is the first time I've tried to
install Apache on this version of Red Hat I suspect that I need an
additional RPM, but I don't know which one.

Thanks and Regards,
Tony

I've been bit by this, insmod/modprobe 100% CPU should be the only
thing hanging the build -- are you on latest applicable RedHat
(kernel?) maintenance?

uname -r says 2.6.18-53.1.19.el5 which I think is the latest release for
5.1.

Thanks,
Tony

Re: configure hangs after checking whether SCTP is supported [In reply to]

Hi Eric,

Our SA confirmed for me that configure spawns "/sbin/modprobe -q
--net_pf_2_proto_132". The modprobe proceses results in 100% CPU usage as
you stated.
I don't see modprobe anywhere under the httpd-2.2.8 directory.

Can you please share the fix for this if you know it?

Many thanks,
Tony
