The error-message comes from the operating system and has nothing to
do with Java/JSCH. See e.g.
http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/not-enough-storage-is-available-to-process-this/9624b57d-ea4c-41fa-aae0-b52e99b69fab
That's the first Google-Hit covering that error-message. As you
can see, the error can also occur on later versions of Windows
and I've seen this kind of error on other operating systems as
well (e.g. with a JVM on a BS2000-system - don't ask ;-)
The way you read in the data is not good practice anyway and can
lead to problems on Windows 7 as well, e.g. if not all data
resides in one TCP-packet and the seconds arrives delayed. A better
approach for that e.g. is
byte[] buf = new byte[maxLength]
int read;
int offset = 0;
while (offset < buf.length && (read = io1.read(buf, offset, Math.min(4096,
buf.length - offset)) != -1){
offset += read;
}
