named hangs on AIX 5.3 after a few days

[Lars-Owe.Ivarsson at its.uu.se]

Hi folks,

named 9.5.0-P1 was started on Thursday (July 24), and appeared to work 
properly for several days.  However, yesterday evening it stopped responding.  
I have included the log for the last two active seconds below.  Unfortunately 
I killed it off somewhat hastily in order to get it running again this 
morning, so I don't have a core file available.

I've compiled bind 9.5.0-P1 on AIX 5300-06-04-0748 with gcc 4.2.2 as follows:

./configure --bindir=/usr/nbin --sbindir=/usr/nbin 
--sysconfdir=/usr/libdata/etc    --enable-ipv6 --enable-threads  
--enable-largefile CFLAGS='-O0 -g -D_LINUX_SOURCE_COMPAT -D_XOPEN_SOURCE=600 
-D_ALL_SOURCE' --with-openssl=/opt/freeware/include/

We experienced a similar behaviour during our upgrade to 9.4.2 some six months 
ago, and tried various combinations of compile options until we reached 
something that appeared stable.  I've used the same configurations this time.

Please advise.

Best regards,
            Lars-Owe
