Probably you have a deadlock for accessing in read/write Lucene indexes on your file system.

Try to increase the maximum number of your file handlers on your operating system.
It seems that you have a problem during the concurrent operation for reading indexes but it depends on your operating system.

Hope this helps.

Thank you for reply
I checked how to increase number of file handlers in UNIX. Probably you are talking about File descriptor. Findings are:

We can increase File handler size at user level.
and session level too.

I will change it at user level and will monitor whether I am getting same error or not. Will let you know soon.

Some more information about same program:
I am running 10 threads to upload documents.
10 separate Java threads are picking up files and uploading documents on Alfresco server.

Now file handler size is :
$ ulimit -Hn
32768
$ ulimit -Sn
32768

Still same error.. Also sometimes below exceptions..

When this lucene related exception occurrs.. other exception also occurs. Otherwise everything goes smooth.
I think root cause is this lucene exception. We took backup of index and restarted as suggested on this forum. Nothing worked.

So any other suggestion (Except upgration of Alfresco version) ?

I noticed your thread was almost 4 years old, but I have the same problem. Did you find a solution perhaps?
