MCP crashes while performing a chunked query (such as 'tmsh show sys connection) that returns a large result if a connection to a TMM is severed (due to a zero-window timeout).
Failover (in a device cluster) or temporary outage (in a standalone system). A core file is generated that has a stack trace that includes a message similar to the following: error reading variable: Cannot access memory at address 0x1.
-- CPU is highly loaded. -- BIG-IP version is v11.4.1 HF9, which includes an incomplete fix for ID 507853 for this issue.
Ensured that MCP no longer crashes when performing a large chunked query and a connection to a TMM is severed. Provides a complete implementation of the fix for ID 507853 on BIG-IP v11.4.1 HF10 and later.
