Note:- It was working fine earlier. I just made one more passive node at TSA. TSA is up & running

This is ehcache.xml file

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="ehcache.xsd" 
         name="BigMemoryMax">
         <defaultCache         
        maxEntriesLocalHeap="0"/> 
        <cache name="PersonCache" maxEntriesLocalHeap="20">

        <searchable/>

        </cache>
        <terracottaConfig url="127.0.0.1:9510" />
</ehcache>

The exact error is at the bottom of the stack trace:

Caused by: net.sf.ehcache.config.InvalidConfigurationException: The disk path for this cache manager is the default path. You must define a specific unique disk path for this manager in order to use restartable caches.

This indicates a configuration issue and given that the configuration you give in your question has no disk component, it means that your application is loading a different ehcache.xml.

Normally Ehcache indicates in its logs which configuration file is loaded. If you do not see that, turn logging level to DEBUG for net.sf.ehcache in your logging framework.
