Yang Yang commented on CASSANDRA-3269:
--------------------------------------
Sylvain:
I did try to move down the threshold to 300MB, but in that case, it does not
seem to occur easily (I haven't seen the issue appear after running under a
300MB threshold for 10 hours).
but if you look at comment
https://issues.apache.org/jira/browse/CASSANDRA-3269?focusedCommentId=13119163&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13119163
you see that LocationInfo being flushed already, twice, once at position 0,
once at 174, then right after that, it tries to discard the segment, but
complains that it's dirty, and the only dirty bit is locationInfo itself. that
is the part that doesn't sound right.
