However, if you have consistant issues with high CPU usage, there is probably something wrong. My experience shows that 98% of the time, the problem is in the code that is running, however, high CPU usage can be caused by many things. First, look in the admin pages.. is your: "Log error messages" and "Catching terminate signal", turned on? Sometimes, if these *trouble shooting* settings are *left on*, these files can grow to be huge and cause problems in themselves. If they are not on, turning them on temporarily can sometimes reveal where issues are. Another common issue may be heavy searches that are hit by SEO bots and other (DOS) type of calls. This can be corrected by dissallowing (perhaps in the robots.txt file) certain process heavy areas of the site. Looking at server managment from this perspective may help: When coding WebDNA, be sensitive to the question: What would this code do if it was hit hard? Other than these types of generalities, it is difficult to troubleshoot webserver problems without some clues... at the minimum, server specs and scope of code that is running on the server. Preferrably, you would have some isolated code.. perhaps using errors found in those two log files that I talked about, to go by. Lastly, the standard WebServer logs are good for checking for heightened traffic, and to what kind of calls, when you are having problems. Donovan -- Donovan D.
