[jira] Resolved: (TS-707) The random number generator from 1-23-2011 is using the same seed for all threads = collisions in the cache

     [ https://issues.apache.org/jira/browse/TS-707?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

John Plevyak resolved TS-707.
-----------------------------

    Resolution: Fixed

svn commit: r1081019

Remove default 'seed' codepath.
Also increase the side of the seed to 64-bits and
use the high resolution timer as part of the seed
for more faster moving bits.
