LockObtainFailedException at new IndexWriter()

I am using Crawler controller to crawl all pages of a medium website. It randomly crawls 2-3 pages and then it causes a lock on the IndexWriter
Directory dir = FSDirectory.open(new File(index));
IndexWriterConfig conf = new IndexWriterConfig(org.apache.lucene.util.Version.LUCENE_41,new StandardAnalyzer(org.apache.lucene.util.Version.LUCENE_41));
writer = new IndexWriter(dir, conf); // line which throws lock exception.
Logs:

Why am I getting this exception? Any help.
UPDATE: 17/08/2014 :
When I run the Indexer first time, it completes successfully with the below exception thrown. If I run the search on this, I get my results successfully. However if I run the Indexer again, it throws the lock exception mentioned above. It also shows that my controller class is called twice.

Quoting the Javadocs -
"Opening an IndexWriter creates a lock file for the directory in use. Trying to open another IndexWriter on the same directory will lead to a LockObtainFailedException. The LockObtainFailedException is also thrown if an IndexReader on the same directory is used to delete documents from the index."
"IndexWriter instances are completely thread safe, meaning multiple threads can call any of its methods, concurrently. If your application requires external synchronization, you should not synchronize on the IndexWriter instance as this may cause deadlock; use your own (non-Lucene) objects instead."
https://lucene.apache.org/core/4_1_0/core/org/apache/lucene/index/IndexWriter.html
Are you creating new instances of IndexWriter for each page that you are crawling?

org.postgresql.util.PSQLException: The connection attempt failed

I am connecting to postgres data base using java web services (apache axis) with JDBC connections to get the data.But suddenly in most of times i am getting an exception of org.postgresql.util.PSQLException: The connection attempt failed. and some times it is working fine. Here I am using many prepared statements. My sample code is
Connection connection=null;
try
{
Class.forName(driver);
connection = DriverManager.getConnection(url, username, password);
ps1=connection.prepareStatement("select * from emp");
rs1=ps1.executeQuery();
while(rs1.next())
{
ps2=connection.prepareStatement("select * from dept where dept_no="+rs1.getInt("dept_no"));
rs2=ps2.executeQuery();
while(rs2.next())
{
................
................
}
}
}
catch(Exception e)
{
System.out.println("Exception occurred is"+e.getMessage());
}
finally
{
try{if(rs1!=null)rs1.close();}catch(Exception e){ System.out.println("*1closing error--->"+e);}
try{if(ps1!=null)ps1.close();}catch(Exception e){ System.out.println("**1closing error--->"+e);}

try{if(connection!=null)connection.close();}catch(Exception e){ System.out.println("***closing error--->"+e);}

I checked the postgres logs and i found the following statements in different cases
1.WARNING: worker took too long to start; cancelled.
2.could not reattach to shared memory (key=...., addr=.....): 487.
3.could not receive data from client: No connection could be made because the target machine actively refused it.
4.unexpected EOF on client connection.
please help me.Thanks In advance

The real problem is:
Caused by: java.net.SocketException: Connection reset
at java.net.SocketInputStream.read
The connection was closed when Java tried to read from it. This can be caused by:
The PostgreSQL server being restarted
The PostgreSQL backend you were connected to being terminated
The PostgreSQL backend you were connected to crashing
Dodgy network connection
Badly behaved stateful firewalls
Idle connections timing out of the NAT connection tables of NAT firewall/routers
... and probably more. Check the PostgreSQL server logs to see if there's anything informative there; also consider doing some network tracing with a tool like Wireshark.

Try chekin Postgresql version, in my case I deployed my app with:
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>42.2.16</version>
</dependency>
But in local I used 42.2.18 and worked fine, so I din't know after checking version, so you should try another versions maybe.

Fixed for me:
hop onto the pg_hba.conf file and under IPV4 connection change its 127.xxxx to the 0.0.0.0/0
double check: hop onto the postgresql.conf and change the listenaddresses to * (im sure you know that you need to delete the starting # first in order to make it work)
Good luck!

But it works fine when I deploy it on my localhost. I tried to find the solutions for this but not getting. So Help me out...

I'm not familiar with this guy "Ebean ORM", but the error track is pretty generic and seems has nothing really to do with "Ebean ORM" itself. Based on my past exp, it is more like a classloader issue. You said it was running fine locally and then? where is it broken? when you have such issues like "NoClassDefFoundError", always check what classloader is being used. And also it is worth to check whether your broken environment has multiple versions of the class/jar as well as if the server has its embedded version of this class/jar.

Custom cursor behavior

And the cursor path is valid, the cursor is visible on app but in log I always find this error. Other problem is that on IE8 the performance is highly impacted only for two custom added cursors. I'm wondering if I must add .cur extension on mime types?
If anyone have e suggestion please let me know, thank you.

So my question would be why are you using java for this you can easily modify your cursor with css, which would be the easiest and best practice as a user can easily disable it if they want.

Has anyone seen this before? Can anyone suggest where I might start looking?

You didn't specify a lot about your setup and what you did in Share before this error occurred so this is my educated guess from the stacktrace:
You perform a site specific search, i.e. the search.js webscript is called with a siteId.
From the webscript the SiteService is called:
at org.alfresco.repo.site.SiteServiceImpl.getSite(SiteServiceImpl.java:894)
The SiteServices tries to read the permissions for the site, when the error occurs:
at $Proxy53.getAllSetPermissions
Is it possible that this is a private site and the user that is running the query has no permissions to access the site? Make sure the users are at least consumers in the site. You could also test if this occurs with public sites as well, or only with private ones.
