samba crashs with 'corrupted double-linked list'

[Jörg Markert]

I'm not a developer hopefully the usage is correct: *valgrind
--trace-children=yes --log-file=/root/val.log /usr/local/samba/sbin/samba*

It took about 4 days until replication stopped working

here is the valgrind logfile
http://paste.ubuntu.com/6028979/

the log.samba
http://paste.ubuntu.com/6029004/

the syslog reports oom-killer at the time replication stopped
http://paste.ubuntu.com/6029096/

after killing all samba processes I run valgrind again and now there are
errors detected (while the replication is still working):
