Memeory Leak in Windows Page file when calling a shell command
I have an issue on our Windows 2003 x64 Build Server when invoking shell commands from a script. Each call causes a "memory leak" in the page file so it grows quite rapidly until it reaches the maximum and the machine stops working. I can reproduce the problem very nicely by running a perl script like for ($count=1; $count<5000; $count...

Odd tcp deadlock under windows
We are moving large amounts of data on a LAN and it has to happen very rapidly and reliably. Currently we use windows TCP as implemented in C++. Using large (synchronous) sends moves the data much faster than a bunch of smaller (synchronous) sends but will frequently deadlock for large gaps of time (.15 seconds) causing the overall trans...

timeGetTime seems to be quite good to query for system time. However, its return value is 32-bit only, so it wraps around every 49 days approx. It's not too hard to detect the rollover in calling code, but it adds some complexity, and (worse) requires keeping a state. Is there some replacement for timeGetTime that would not have this w...
