Since the livecycle is eating so much of space our server got full.
I have delete some of the files from the DocumentStorage path that too old dates.
Please see the error message.
How do I rectify this problem, I need to import the .lca files.
Well, you should never delete any file from GDS directory manually.
If you have to clear up the space on server, make sure you use the purge utility provided with LC to remove old processes and files.
The only recommended way to get out of this situation is to restore the files that you have deleted from that directory. (if you have taken a backup of those files before deleting)
Thanks for the response.
I will look into it.
