Strange Issues

--------------------------- My System: A dedicated server with: Red Hat 7.2 P4 2 GHZ 1GB Ram -Apache -PHP 4.2 -MySQL Ensim panel --------------------------- I am having strange occurrences of people telling me they cannot sign into their accounts. It happens every now and then, and it happens to anyone -- but not everyone. I am not sure what this could be a result of. I start to think it's a server issue. I see no common pattern, they are using either windows 98 or XP with IE 5 and 6. I personally run XP and have the same setup as some of these that report trouble signing in. If they try to sign in later, they get in fine. I run several sites on this server, and this particular site is high traffic. My other site has just about 30 members and I have had not a single complain in 6 months. So I'm baffled. The hour of the day varies,as well. There's no regular or common pattern that I can see. Could it be from an issue with Apache, MySQl and PHP? Maybe it is even an issue with PHP sessions. I wondered if anyone else has heard of or experienced something similar. If so, have you figured out what is causing this? Have you found a workaround? Thanks! -- Nicole
