Service/Keepalive is down or dying, but keepalive error of OK

I have loads of services (port 80 & port 443) running on my two redundant 11503s, and I am using a keepalive type of http HEAD, non-persistant with a keepalive uri. The keepalives are getting through fine and are receiving the correct response code, but the services are constantly changing state between alive, dying and down. When the service is down or dying the keepalive error still says "OK":

CSS11503# sh keepalive AUTO_XXXXXX

Name: AUTO_XXXXXX Index: 227 State: Down

Description: Auto generated for service XXXXXX

Address: X.X.X.X Port: 80

Type: HTTP:HEAD:/keepalive/keepalive.jsp

Keepalive Error: OK

Encryption: Disabled

Frequency: 5

Max Failures: 3

Retry Frequency: 5

Dependent Services:

XXXXXX

Do you have any idea of why this could be happening? Also, is there a limit on the number of services/keepalives you can run? When i do a show keepalive, it lists 277 different keepalives (all AUTO ones).

The limit of http keepalive is 256.

But if that was the problem, the CSS would prevent you to configure it.

However, your frequency could be a problem.

You may have to increase the frequency interval.
