    <ERROR> Failure invoked by Data Adapter

    I use lighstreamer with Socket Programming. I put lightstreamer on Windows and it work fine.

    Now we have change server to Linux. Everything is going fine, until I send item with code minus "-", like TMPI-W. Server suddenly stop with Error Warning below :
    21.Apr.10 11:49:46,274 < WARN> Received Remote Server message: '0|S|stock_name|S|TMPI-W|S|last_price|S|2375|S|time|S|11:50:43|S|pct_chan ge|S|0|S|bid_quantity|S|52529|S|bid|S|2350|S|ask|S |2375|S|ask_quantity|S|874|S|min|S|2375|S|max|S|24 25|S|ref_price|S|2386.57|S|open_price|S|2425'

    The message in the reported warning, indeed, has a wrong syntax, but this is because of the initial part, which was supposed to contain a message type, like UD3
    (note that a heading timestamp should have been already consumed before).

    The reported exception occurs 4 seconds later, so it may be related with a different line.

    You can have the Server log the lines it receives by setting the com.lightstreamer.adapters.remote logger at DEBUG level.
    Then, we can check what exactly causes the exception.

    I Found The Problem

    I found the problem, it seem there is some line with no value in messaging format. Like "||", it should be "|withvalue|".

    In Windows 2003 it work fine, but in Linux Debian this is a problem, but I handle this with code inside socket sending application.
