Problem Symptoms:
The $LOGDIR/z39_server_9991.log file  has:

z39_server(1) [warn] Scan: communication failure (code -5)
ERROR 2+ Temporary_system_error 0 - 1+
or
z39_server(425) [warn] Search: communication failure (code -7)
or
"Search was a bloomin' failure"  or  "connect: Connection refused" errors.

Cause:
1) In $alephe_tab/z39_server/z39_server.conf, the pc_server port number was incorrect.
It is currently set to:
hostname localhost:6991
While your pc_server port is "6992".
2) The pc_server which should be running on the port specified in $alephe_tab/z39_server/z39_server.conf file is not running or is blocked.

Resolution:
Check/correct the port number and restart the z39_server and the pc_server.
