--------------------------------------

             Summary: Thrift daemon is crashing the server
                 Key: CASSANDRA-4856
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4856
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 1.1.6
         Environment: MacOS 10.8.2
            Reporter: Michael Yeh


I'm new to cassandra and was looking at using the kundera thrift client.  I was able to get
the sample code working without any issues.  After upgrading to mountain lion on my mac, I
didn't realize I had lost the /var/lib/cassandra directory.  When I tried to run the previously
working sample code, it would crash cassandra with the following stack trace:
INFO 12:55:37,147 Listening for thrift clients...
ERROR 12:55:43,545 Exception in thread Thread[Thread-3,5,main]
java.lang.OutOfMemoryError: unable to create new native thread
	at java.lang.Thread.start0(Native Method)
	at java.lang.Thread.start(Thread.java:658)
	at java.util.concurrent.ThreadPoolExecutor.addIfUnderMaximumPoolSize(ThreadPoolExecutor.java:727)
	at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:657)
	at org.apache.cassandra.thrift.CustomTThreadPoolServer.serve(CustomTThreadPoolServer.java:103)
	at org.apache.cassandra.thrift.CassandraDaemon$ThriftServer.run(CassandraDaemon.java:213)

After realizing that I needed to recreate the keyspace and column families, everything started
to work again.  Although I'm no longer blocked with my issue, no clients should ever be able
to crash a server even if it is user error.
