You can track all active APARs for this component.

 

APAR status

  • Closed as program error.

Error description

  • Error Description￘
When the Datapower appliance is configured to use SSLProxy to
handle traffic, having slow DNS responses may cause the
appliance to restart.

Local fix

  • Local Fix￘
Changing the system to use a fixed TCP/IP address rather then a
hostname may avoid the problem from occurring. If the traffic
being handled by SSLProxy is HTTP, then using a XMLFirewall
instead of SSLProxy may prevent the issue from occurring.

Problem summary

  • Affected are customers of all firmware releases, using SSL Proxy
service with a backend specified as a host name, resolved via
DNS.

In some cases, especially if the DNS lookup is slow, the
appliance may hang for about two minutes and ultimately restart.

Problem conclusion

  • The fix is available in 4.0.1.12, 4.0.2.8 and 5.0.0.1

Temporary fix
