Memory is allocated for the list of connections that serve as the basis for the host list that is sent to the TKEGRID extension. A memory request occurs for each request that goes through the grid load-balancing algorithm. However, that memory is never freed, which creates a memory leak.

There is no solution or workaround for this problem.
