[jira] [Updated] (CASSANDRA-3402) Runtime exception thrown
periodically under load
[ https://issues.apache.org/jira/browse/CASSANDRA-3402?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andy Stec updated CASSANDRA-3402:
---------------------------------
Attachment: system.log.gz
Hi Sylvain,
Looks like assertions are enabled:
# enable assertions. disabling this in production will give a modest
# performance benefit (around 5%).
JVM_OPTS="$JVM_OPTS -ea"
The exception always says "error reading 5 of 5". We don't have a way of
reproducing the problem on a blank database. The exception is thrown after
load runs for several hours. I attached the full system.log.
Thanks,
Andy
