Hello,

we migrated from official 2.3.6 to 2.3.6-srh-extra , released on Thu. IO went nicely down as expected, unfortunately large memory-leak occured

• it doesn't happen (so much) on node having only 1 r/w intensive table - primary replica. Removed secondary replicas, so the usage went down.
  

• other nodes having multiple primary/secondary replicas keeps rising in memory usage since deploy
  

Build is made from release https://github.com/srh/rethinkdb/releases/tag/v2.3.6-srh-extra +patch de5d96e .

• Debian Stretch, cache-size=4096 (datadir is not large, partition usage 2.8G), no configuration of user_value
• gcc build rised segmentation fault during linking, didn't finish (same problem when trying to build official 2.3.6)
• clang build completed - missing web_assets in release were built using nodejs from nodesource.com
