Hi,
I just tried updating to 2.1.1 on my test instance and none of the
incoming data is being written out to disk.  It worked for me with
2.0.9.
The problem is with the log_iw_size() parameter in my tcp source.
Without it, the data is being logged to disk.
My configuration file is below.  Anything obviously amiss?
Thanks,
Joe

hmm... if SQL is not being used syslog-ng is compiled in non-threaded
mode, in which case the counter used for the window size is 16 bits,
cutting the high order bits, thus resulting in a zero window size. This
obviously will not work really well.

I've pushed a patch to make this a 32 bit value, in the 3.0 branch I
already made the same change, albeit for performance reasons.

    changed GAtomicCounter type to gint instead of guint16 to allow window sizes larger than 65536
    
        This also synces syslog-ng with the 3.0 branch, where this is already gint instead of guint16.
