If MDS connection is used, and mds connection failed to open there will be 128 bytes memory leak every time. for example an irule using hsl like : when CLIENT_ACCEPTED { set hsl [HSL::open -proto UDP -pool pool_hsl] log local0. "$hsl" HSL::send $hsl "foo" } To cause mds connection fail, the easiest way is to use an HSL pool server to which the BIG-IP has no route.
memory leak
Using mds connection such as HSL command in irule. mds connection fails
avoid using HSL irule. Or fix configure to make mds connection always success
Using MDS connection will not leak memory any more.
