Hi,

OS : HP Unix - 10.0,
Sybase : 11.5

My Application (using DB-Lib, with c- program) to nnect to the sybase server. ONLY SOME TIMES the program fails (report genaration/data upload) with error:

DBERROR : id [20018] SQL server is unavailable...
OSERROR : cannt assist the interface..
Incorrect Login/password :

or

DBERROR : id [20018] SQL server is unavailable...
OSERROR : Id [-1]
Incorrect Login/password :

AND
error in the SQL error log "Kernel Cannot read, host process disconnected"

Any query passes to ISQL/SQL Advantage is successful. Only with program it fails.

Any suggestions are welcome.

Best Regards,

Madhu
