Can do, its not in production yet. I did install 1.6.0pre4 on it, and that one runs fine btw.
Removed 1.6.0pre4 and configured with --enable-debug:
./configure --enable-transarc-paths --enable-namei-fileserver --with-afs-sysname=amd64_fbsd_80 --enable-largefile-fileserver --disable-pam --enable-supergroups --with-krb5-conf=/usr/bin/krb5-config --disable-kernel-module --enable-debug
Ran locally with localauth 'bos listkeys localhost -localauth' 20 times, no problem
Ran it remote 2 times and it crashed on 2nd attempt, remote got this error:
bos: communications failure (-1) error encountered while listing keys
On server there is noting in BosLog other then

Did same test with remote bos getlog on this small BosLog with just 1 line, crashed also on 2nd call, similar backtrace from core file.
Ran it with bigger log file (copied the config.log to BosLog and did a get BosLog.old after starting bosserver), this one crashed during the log transfer. Console printed about 1417 bytes from the file. Again same backtrace from the core.
If I run the getlog local on the server with localauth it works fine.

I cannot reproduce this any more with the old key file, so must have been something else (might have ran it without localauth or mixed up something.
