I work for an ISP with about 75,000 users. The user information is stored in and ldap database which freeradius uses to authenticate against. On a fairly regular basis I've been seeing radius timeouts for no appearent reason. It doesn't seem to be a server load issue and nothing is showing up in the logs. I've noticed that it seems to be pretty consistant time wise. Some people have reported it happening every hour or so and it seems to happen almost exactly an hour after it happened the previous time. for instance, if it first happend at 10:38am, it would most likely happen again at 11:38am. It's usually being noticed on email clients as they check email on pretty regular basis.
My question is, has anyone else noticed symptoms similar to these? I know it seems pretty strange but I figured I'd check. I'm working on setting up monitoring and possibly a little more verbose logging but thought asking here might help point me in the right direction. System information below. OS - freebsd 4.10 freeradius - 1.0.1 openldap - 2.2.19 load on the box is pretty low so that shouldn't be an issue. Joe H. - List info/subscribe/unsubscribe?
