[jira] [Commented] (CASSANDRA-7387) corrupt startup-commit-log
causes hang on startup
[ https://issues.apache.org/jira/browse/CASSANDRA-7387?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14029563#comment-14029563 ]
Brandon Williams commented on CASSANDRA-7387:
---------------------------------------------
You should probably try upgrading, cassandra doesn't care about zero-length commit logs. strace isn't really the right tool to troubleshoot java, a thread dump from jstack -l <pid> is more useful.
