New Post: Invalid Rar Header: 174

I sometimes do get " Invalid Rar Header: 174" exceptions, when I do process RAR files.
The rar files are ok. I basically scan for interesting data in the binary streams of
all files in a rar file.

fileStreamIn = new FileStream(fileName, FileMode.Open, FileAccess.Read,FileShare.ReadWrite,1024222222,FileOptions.SequentialScan );
reader=SharpCompress.Reader.ReaderFactory.Open(fileStreamIn,SharpCompress.Common.Options.LookForHeader);

while ( reader.MoveToNextEntry())
{
if (!reader.Entry.IsDirectory)
{

entryStream = reader.OpenEntryStream ();
if (entryStream.CanRead)
{
logfileParser.ProcessStream(entryStream);
 } 

}
}

This is the exception:
: Invalid Rar Header: 174
