It could be a case of
1) an endless loop, the file limit you've set is quite high (799969), I
doubt that so many open fd's are needed at any point.
2) missing file close after in some error path
The file's are open via
send_write
open_cur_inode_file
dentry_open
and closed from callbacks in close_cur_inode_file.
Case 2 looks more realistic, but I don't have an idea what could go
wrong.
