Hi Frnds,

We got alerts when we checked various pages and most were slow and returned an Apache error.
I restarted Apache and it is now OK.

This is error we are getting:
---------------------------
Service Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Apache/2.4.9 (Win32) OpenSSL/1.0.1h Server at www.xyz-lmn.com Port 443

When I checked the error logs from around teh time of such error i see below:

Do you run apache as reverse proxy?
