Background
ODBC allows to specify a connection timeout (in milliseconds).
CONNECTTIMEOUT=0 means no timeout.
Description
Client connections using ODBC with connection timeout defined as no timeout (CONNECTTIMEOUT=0) may return "Connection attempt timed out."
Workaround
Use the default or specify a non-zero value e.g.: CONNECTTIMEOUT=2000.
Fix
ODBC connections with CONNECTTIMEOUT=0 are treated correctly as no timeout.
