samba - Jun 2003 - Call timed out/session request failed Samba 2.2.8a on SVR4 System

Hi,

we use on an siemens rm400/E70 (Reliant UNIX 5.44) samba 2.0.6. All works 
fine.
Because of recurity reasons we plan to use 2.2.8a.
There were only minor problems compiling the sources, smbclient -L <any 
other host> works well, smbd and nmbd starts with the smb.conf from samba 
2.0.6 without any serious messages

Starting smbclient -L <NB name localhost=TCPPS02> results in the following
messages:
added interface ip=172.16.207.7 bcast=172.16.255.255 nmask=255.255.0.0
session request to TCPPS02 failed (Call timed out: server did not respond 
after 20000 milliseconds) 
session request to *SMBSERVER failed (Call timed out: server did not 
respond after 20000 milliseconds) 

ps shows then 3 smbd processes, smbstatus: no used services, no locked 
files

in the log-file log.smbd (log level=5) these warnings are recorded
[2003/06/25 12:54:10, 5] lib/util_sock.c:print_socket_options(109)
  Could not test socket option SO_SNDTIMEO.
[2003/06/25 12:54:10, 5] lib/util_sock.c:print_socket_options(109)
  Could not test socket option SO_RCVTIMEO.

Any ideas, any hints ?

Thanks
