Under load, we > have seen high cpu loads and very slow time to serve times when allocating IO > buffers and marking them with this flag. We have had to disable calls to > madvise() in ats_madvise(), rebuild and redeploy to fix this problem. We'd > like to make the use of madvise() with the MADV_DONTDUMP option configurable. > The PR associated with this ticket uses a patch from TS-3417 that implements > making MADV_DONTDUMP configurable. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
