[mono-android] Random exceptions while reading SSL stream

[Piotr Kryger]

Hi,

Im trying to read binary data from ssl stream.
Basically, I do this:

Stream inner = ConnectToMyHttpsServerAndGetStream();
SslStream sslStream = new SslStream(inner, false, null, null);
sslStream.AuthenticateAsClient(certificateServerName);
BinaryReader reader = new BinaryReader(sslStream);
//calls to reader methods go here
reader.Close();


Most of the time, code runs fine, but sometimes during reading
operations my app freezes. Log shows following (or similar)
stacktrace:
11-17 09:28:20.084 I/mono    (24066): Stacktrace:

The more data is read, the more frequent the exception tends to be.
Is there anything I can do to workaround this issue? Or maybe Im doing
something wrong?
Im using M4A 1.2 and VS2010.

Thanks,
Piotr
