Root Cause Analysis
The vulnerability stems from the HostController's persistent reconnection attempts creating unclosed connections. The primary indicators are:
- HostController$ReconnectTask.run() - Directly referenced in Red Hat's WFCORE-5105 as the looping reconnection mechanism
- ManagementClient.establishConnection() - Core connection creation point called during each retry
- ProtocolChannelClient.connect() - Low-level network resource allocator for management channels
These functions would appear in profiler stack traces showing repeated connection attempts without corresponding cleanup. The patch likely added connection.close() calls in ReconnectTask and proper error handling in ManagementClient.
