Robert Stupp updated CASSANDRA-13345:
-------------------------------------
         Labels:   (was: easyfix)
       Priority: Minor  (was: Major)
    Description: 
Hi All,

I followed the below steps 

```
$ git clone https://github.com/apache/cassandra.git
$ cd cassandra/
$ ant
$ bin/cassandra -f

The stack size specified is too small, Specify at least 328k
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
```

After getting this , i had to upgrade the thread stack size to 512kb in 
'conf/jvm.options'
```
$ git diff conf/jvm.options
diff --git a/conf/jvm.options b/conf/jvm.options
index 49b2196..00c03ce 100644
--- a/conf/jvm.options
+++ b/conf/jvm.options
@@ -99,7 +99,7 @@
 -XX:+HeapDumpOnOutOfMemoryError

 # Per-thread stack size.
--Xss256k
+-Xss512k

 # Larger interned string table, for gossip's benefit (CASSANDRA-6410)
 -XX:StringTableSize=1000003
```
Thereafter i was able to start the Cassandra server successfully.
Could you please consider increasing the stack size to '512k' in 
'conf/jvm.options.

Similar to  "https://issues.apache.org/jira/browse/CASSANDRA-13300";. Let me 
know if we can increase the stack size in the Apache Cassandra trunk.

Thanks for support provided so far , and let me know

Regards,
Amit

I think this change should not go in as it stands. Although it might help 
getting C* running on a currently unsupported architecture, there is just no 
need to change this for existing users.
