When I started using IQFeed, my computer was nearly out of memeory. I had various problems. After I doubled the amount of RAM to 4 GB, turned off the real time virus checker, and generally went through the process list and disabled / removed all unnecessary programs I've had no problems since.
Another thing I did was to separate the real-time database and historical database. My RT DB was created with a minimum number of bars to correctly calculate my indicators. When I'm trading I don't care what happened last week or last month. I have a second DB that has a much larger number of bars that I update after market hours that I use for backtesting and code development. This greatly improves the execution speed during market hours.
Finally, the RT computer is generally left alone. I'm writing this reply on another PC where I surf the net, read email, run TurboTax etc.

Sometimes it is memory running out, and I am aware of that, but there also are other times when simply dragging a scroll bar in the symbol list window pane caused it to crash. There may be other actions that cause the crash, but they seem to involve interacting with the main AmiBroker window's user interface while the IQFeed plugin for Amibroker window is up and retrieving data at the same time. Also, sometimes it seems that retrieving data for more than one symbol simultaneously causes the crash. Perhaps its a threading issue? I saw some old posts reporting similar problems, but no resolution.
