    Affects Versions: 1.7.0
            Reporter: roger

I fond a bug of this tailsource.
When I use the regular expression to match files under a folder. when some of 
file was rolling by log4j, this file's start position which is used to record 
tail position will be setted to 0. And then all of matched files will be readed 
after checking the code. I find below info:
The process() will update all of inodes info by 
But the the skipToEnd will be setted to "false" when update this file.
" public List<Long> updateTailFiles() throws IOException
{ return updateTailFiles(false); }
when this file was rolled. below code will be executed. this startPos will be 
setted to 0. It will be readed again.
if (tf == null || !tf.getPath().equals(f.getAbsolutePath()))
{ long startPos = skipToEnd ? f.length() : 0; tf = openFile(f, headers, inode, 
startPos); }
Does anyone occurred same problem or is there any setting I missed?
