Hi to all.

We have a problem backing up remote mounted files on a MacIntosh ADSM client. 
If we run an incremental backup against local files, everything works fine. But 
using the MAC file services to mount folders from a remote MacIntosh and then 
running a incremental backup against these files, causes the local MAC to crash 
by displaying the well known "MAC-bombs" and a window with a message 
"System-Error 11". We then have to reboot the local computer. The same thing 
happens, if we mount folders from a central data repository on a AIX-server 
using the AIX-Connection's AT-Services. The only error message we get in the 
server's activity log is:

"ANR0481W Session xxx for node yyy terminated - the client did not respond 
within 600 seconds"

If we do a selective backup the error does not appear and all selected files 
will be backed up correctly.

We have tried to change the values of different parameters of the client option 
file (TCPBUFFSIZE, TCPWINDOWSIZE, SLOWINCREMENTAL), but nothing was useful ...

ADSM-Server: Version 2.1.0.5 running on a RS/6000 SP2-node; AIX 4.1.4
ADSM-Client: Version 2.1.0.6 running on a PCI-Power MAC 7500/100; MacOs 7.5.3 
German
Communication: TCPIP over 10Mbit Ethernet

How can we avoid this problem ? Any idea ?
