a) How much is the amount of RAM on your index server?
b) How much is the Hard Drive Space on the drive where Index location is set to?
c) Check from Central Admin --> Operations --> Services --> is the Search service running? There are two of them i.e. Windows SharePoint Search and Office SharePoint Server Search

a)Index server are the same server where my application host.ite ram size is 4 gb.

b)Hard drive space more than 100 gb.

c)both the services are running state.
seems that you created Crawling policy for both incremental and full crawl

i think if you check the space inside the folder that contains the index service you will find that the drive is almost full, this occurs if the full crawl is repated so much.
so i suggest to change the index folder to another drive or server this can be achieved from central administration or to stop the full crawl.
