      Description

      Hi!
      I use readwritesplit router on maxscale-2.3.9, but problem can be reproduce on maxscale-2.3.11.
      Kernel: 3.10.0-957.12.2.el7.x86_64

      UPD: My configuration use keepalived(active - passive), I see memory leak on passive node too.
      UPD: add valgrind ms_print result to attach (massif test)
