Dear develeoper:
The problem is only one: chan_h323. It is a deffective software, at least
in 64 bits. Without it Asterisk is perfect. I had to remove it because
every time I typed "core show channels", it locks up and I need to
disconnect and reconnect. Furthermore, it must have a memoryleak, for there
are two kernel-wide variables variable called numothersock and dgramrcvbuf
that keep growing for ever when chan_h323 is used a lot. With SIP-to-SIP
none of this happens. It seems to use-up resources but does not release
them. It may not be even chan_h323's fault, but the openh323 libraries. I
am looking for a replacement for chan_h323 and the libraries. I don't know
how to debug it and I cannot certainly risk more downtime. After a few
hours Asterisk becomes unresponsive, maybe because the resources have been
exhausted. Valgrind cannot be used because it does not understand the
multimedia instructions used by the codec translators. I already filed a
bug and Julian (the valgrind creator) os looking at it.

Please close the case, unless somebody wants to take control of the box
and I can send a few thousand h323 calls and we can get to te bottom of
this. I feel, though, that Asterisk does not consider h323 important, but
there are hundreds of dialers out there that use H3323, exclusively.
