Hello,

I have a problem with our Sun-Server (SunOS 5.8 Generic_108528-14 sun4u
sparc SUNW, Sun-Fire-280R).

Wenn I try to transfer files from another or the same network to this server
it takes a long time AND during oracle database import I got an internal bus
error.

I checked the alert.log file of Oracle and I read the following error:

could somebody tell me what the problem is. What should I (un-)configure on
the sun machine?

Thank you very much in advance.

Kind regards,
Hicham
