    Description

      Issue Status as of Nov 21, 2018

      ISSUE SUMMARY
      MongoDB may cause excessive disk space usage when Zlib compression is enabled.

      USER IMPACT
      Disk space could be consumed rapidly causing out of space errors. Upgrading to a version that contains the fix will not reclaim the excess disk space; for that, a re-write of the collection data with a version containing the fix is needed (e.g.: initial sync).

      WORKAROUNDS
      There is currently no workaround for this issue.

      AFFECTED VERSIONS
      MongoDB production releases 3.6.0 through 3.6.8 as well as 4.0.0 and 4.0.1 are affected by this issue.

      FIX VERSION
      This issue is fixed in MongoDB version 3.6.9 and 4.0.2

      RESOLUTION DETAILS
      Please consider upgrading to 3.6.9 or 4.0.2 if this issue impacts you.
