 Ok, I've now done some further tests and I've found the reason, why
my application process was not able to continue ....

 The reason was, that the backend process terminated when the isdn
line went down.

 What have I done:

 telnet to remote server pc and start the postmaster.

 Now doing several sql-command using psql ...

 now do nothing, line is dropped ....

 now I try to execute some psql commands .. but they failed.

 telnet to server: postmaster is still running, but backend process is
not there ...


 Any idea ?
