WIn 2k AS running an WLBS web farm. The load is balanced equally. On weekdays
I get between 50000 to 100000 hits on each server. About 70% of that is
static content.
One of the servers is logging asp_0147|500_Server_error in some of the ASP
apps. I also notice that once the 500 error is logged I cannot open the
property page for any IIS VD in IIS Mgr mmc on the affected server. It thinks
the page is open but I cannot see it. Yesterday I got proof that this is
occurring more than it appears in the IIS Logs. (So IIS is failing to log all
occurrances of this error!) The requests fail to be logged at all!
I have to reboot the server to clear the problem but it comes back after a
few days. I installed latest updates on 6/22 and this started on 7/5 (that is
I first see it in the logs on 7/5).
We have another individual win2k IIS server running a 3rd party product. It
was also updated on 6/22 and is generating a lot of 500 errors now. The thrid
party app is an isapi application that runs db queries. It makes me wonder if
this is related?
Any ideas? How do I fix this?
Thanks in advance.
