Hi,
I recently faced an issue with the lucene writer giving me null pointer exception in the logs.
Due to this the logs file got upto 10 gb in size which led to disk space shortage of the server.Which ultimetly led into the crash of the server.
I have attached the code of the errors from the logs for more information.
On analysing the error logs i came to a conclusion that this error occurs when i try to update any liferay core tables(like adding new user,adding new document etc.).
