INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10

The listener thread may receive an OS error when trying to bind
the port with an IPv6 address. This results in an AF similar to:

Assert Warning: Unable to bind to the port (18105) on the host
() for the server (server1).

This may occur when using a specific IPv6 address other than the
loopback address ::1.

This problem may occur on releases of Linux where the option
"myhostname" is permitted for the hosts entry in
/etc/nsswitch.conf. The presence of this entry avoids the need
to enter the host's specific IP address into /etc/hosts and will
result in an IPv6 address being used by the listener thread if
IPv6 has been configured for at least one network interface. Red
Hat 7 is one such OS version where this option is available.

****************************************************************

The workaround is to allow the bind operation to use any of the
available IPv6 addresses on the server by prefixing the hostname
or address in column 3 of the sqlhosts file with an asterix "*".
Alternatively if IPv6 is not required it may be disabled by
setting the environment variable IFX_DISABLE_IPV6 or creating
the empty file $INFORMIXDIR/etc/IFX_DISABLE_IPV6.
