APAR status

  • Closed as program error.

Error description

  • When using a Load Balancer Group (LBG) to dynamically retrieve
Workload Management Information for WAS (WebSphere
Application Server) cell members, an unexpected restart can
occur if the next LBG member is chosen at the same time that
DataPower detects a WAS cell member has went down.

Local fix

  • Create an LBGroup with static members (as opposed to the WLM
dynamic members)

Problem summary

  • Affected are DataPower customers using Load Balancer Groups
enabled to retrieve workload management information

Problem Summary:

Restart might occur if a load balancer group member is removed
from the group while requests are being routed to this member.

Problem conclusion

  • The fix is available in 3.8.2.12, 4.0.1.10 and 4.0.2.6.

Temporary fix
