I had this one.
We were using mSQL in the 90s for web projects. A very important customer wanted a "real" database so we bought DB2. Because we didn't have an IBM plattform or Solaris we went with Windows NT.
Everyhing went fine, until one day we recognized the website being slow. Investigating brought the database as the culprit. So I went there and logged into the NT box in the data center and checked the DB2. Everything was fast. Back to my desk and the database was slow again after some time. Back to the NT server and the same thing happend.
After quite a long time I found the real culprit. The NT pipes GL software render screen blanker. After some time without interaction the screen blanker started up and took all the CPU. So the database and the website went slow. Someone had set the screenblanker to the nice GL pipes renderer.
[Searching the web, IBM introduced DB2 for Windows NT 31.10.1995 and I went to Cebit that year to check it out]
This reminds me a nice day we spent at customer's premises trying to figure out why DB2 won't install or start properly on a win2k box. Weird error messages etc. Problem was that it didn't like that the box was named 'DB2'...
