Re: Client app hangs in the debugger

Hi,

The lockup occurs in the MSVC debugger, Borland C++ Builder debugger and
standalone.  When running standalone, the lookup occurs when Windows is busy
performing operations.

Regards,
Jae

Does this only happen when you use the MSVC debugger? I mean, is this a
RoadRunner problem or a MSVC problem?

I haven't noticed this when debugging RoadRunner in Linux.

RoadRunner uses GCond to synchronize threads, the MSVC debugger might have
some problems with them.

No, currently the functions will block until the operation is done or until
the TCP connection times out. But a selectable timeout value would be nice.
