2009Q4: apache22 (devel/apr) bug on solaris X86 32Bit

[Harald Strack <strack%hm.edu@localhost>]

Hi,

when I was running apache22 with mod_proxy or mod_jk in conjunction with
tomcat the server seg faulted, and the following messages appeared in
the error log

[Wed Feb 24 10:53:37 2010] [notice] child pid 27462 exit signal Segmentation 
fault (11)
[Wed Feb 24 10:53:37 2010] [error] (11)Resource temporarily unavailable: 
apr_pollset_poll: (listen)
[Wed Feb 24 10:53:38 2010] [error] (11)Resource temporarily unavailable: 
apr_pollset_poll: (listen)
[Wed Feb 24 10:53:38 2010] [notice] child pid 27482 exit signal Segmentation 
fault (11)
[Wed Feb 24 10:53:38 2010] [notice] child pid 27475 exit signal Segmentation 
fault (11)

and the server did not respond in a decent time.

There seems to be a bug in apr's port_getn or the underlaying solaris kernel 
function, as mentioned here:

https://issues.apache.org/bugzilla/show_bug.cgi?id=48029

An appropriate patch is offered there, too:

http://svn.apache.org/viewvc/apr/apr/branches/1.3.x/poll/unix/port.c?r1=807269&r2=829803

I added the patch to devel/apr as devel/apr/patches/patch-aa
