When rejecting non-TCP/UDP inbound traffic a small amount of memory is leaked with each packet. Depending on the volume of such traffic this may be a slow or fast leak.
TMM might eventually run out of available memory. The aggressive mode sweeper might be triggered, causing connections to be killed. Eventually TMM restarts.
CGNAT configured with inbound connections enabled or hairpinning enabled Non-TCP/UDP traffic with a destination in the LSN Pool address space
None.
This release fixes a memory leak that occurred When rejecting non-TCP/UDP inbound traffic.
