This question covers both serverfault and stackoverflow, so I just chose this one.
I get the following exception with a simple file copy code. Its launch on Windows Server 2003 x64
Caused by: java.io.IOException: Insufficient system resources exist to complete the requested service
at sun.nio.ch.FileDispatcher.pwrite0(Native Method)

at Tools.copy(Tools.java:473)
public static void copy(FileChannel input, FileChannel output) throws IOException {
final long size = input.size();
long pos = 0;
while (pos < size) {
final long count = (size - pos) > FIFTY_MB ? FIFTY_MB : (size - pos);
pos += output.transferFrom(input, pos, count);
}
}
The fact is that the server that runs this code is completely new and super powerful, so I don’t understand which system resource it can run out of.
It looks like the error described here:
http://support.microsoft.com/kb/304101
But I tried to add changes to the registry to increase the size of the kernel memory page, and this did not help.
, , , FileChannel transferFrom 50 . , 1 . , , 32 !
? FileChannel Windows?
