Error description
Communications Server for Windows, Version 6.1.3 & 6.4 ------------------------------------------------------ When a network outage occurs and CP-CP sessions have failed, they should immediately attempt to recover once the link recovers or to activate on an alternate link if one is active. Under some conditions, such as the remote host being slow to respond, the activation attempts may time out; after a few failed attempts, no more attempts will be made. This leaves the node without CP-CP sessions, so no other sessions can be activated.
Local fix
Stop/restart the node.
Problem summary
USERS AFFECTED: All users. PROBLEM DESCRIPTION: See error description, above. PROBLEM SUMMARY: When a link becomes active, an attempt is made to establish CP-CP sessions as follows: - timeout in 5 seconds if unsuccessful - retry 5 more times - wait 30 seconds - try to activate CP-CP sessions over each active link in turn, starting with the one(s) marked as preferred NN server, with 6 5-second timeout periods each - This last step will continue to occur at 30 second intervals until CP-CP sessions are successfully activated. The problem is that the initial 30-second timer failed to trip, so the subsequent retry attempts never occurred.
Problem conclusion
The root cause has been identified and corrected. This problem appears to have been introduced by changes made for APAR JR26404.
