} Okay, so it's not the upgrade itself that's wrong.

} That's likely the problem.  Libpthread *must* be loaded from the
} very start of the program.  It can't be initialized later on, AFAIK.

     libpthread overrides some entry points in libc, so you're either
linked against libpthread or not.

} This is probably a packaging issue then.  If you can get the sendmail
} binary linked against libpthread, that should probably solve the issue.

     No, you can't.  sendmail uses _res which isn't thread safe.  Since
db3 and db4 are both linked against pthread, that means you can't use
either one.  Try removing SASL_DBTYPE from mk.conf.
