samba - May 2007 - Software caused connection abort on 3.0.23d Solaris 9

The archives said that if I had an old version of smbpasswd generate my
samba passwords that I would need to correct the LCT fields.  The samba
passwords were generated with 3.0.23d which is new enough, but my samba
log is full of these errors.

[2007/05/21 07:59:37, 0] smbd/server.c:open_sockets_smbd(443)
  open_sockets_smbd: accept: Software caused connection abort
[2007/05/21 08:31:46, 0] smbd/server.c:open_sockets_smbd(443)
  open_sockets_smbd: accept: Software caused connection abort

Any ideas?

Here is the output from testparm:
