I'm having a problem with my SPS v1 server where the web service stops every 1-2 hours. Nothing in the event log looks unusual, just a bunch of incorrect logins (usually spelling error jsmth instead of jsmith for example). The web service automatically restarts its self about 50 times or so, then it give up and I have to reboot the box. I'm sure somebody else has had this problem, but I can't seem to find anything about it.
