Subject [jira] [Commented] (IGNITE-3810) FileSwapSpaceSpi can hang when large value is written
Date Tue, 13 Sep 2016 15:25:21 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-3810?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15487507#comment-15487507

Valentin Kulichenko commented on IGNITE-3810:
---------------------------------------------

Dmitriy, can we automatically increase the queue size in this case? This definitely should
not hang. At the very least we should throw an exception with a proper message, but this is
not good either because the fix will require full cluster restart.

> Weirdly, the value of size {{1024 * 1024 - 48}} is successfully written, but when it
is only one byte bigger, the swap space hangs.
