Hi All

My ncsd host cache value is

"positive-time-to-live hosts 3600"

My licence-servers needs to failover in less than 5 minutes,
Which requires a Considerable reduction in host caching.

Are there any rules-of-thumb regarding , how low it can go ?

Best Rgds
Rob

Dear all

Our NMS running SUN OS experienced some tech. problems
recently where e-mail are not getting sent and kept
building up consuming a lot of CPU and space (a lot of
process running sm_notify and sm_server and the mailq
totaled to more than 4500).

We tried to investigate and did not find fault on
either the NMS applications or the mail server because
when we rebooted the server back, it started sending
all the e-mails that are waiting in the queue

can any one suggest...what all i need to check to
resolve the issue.

Thanks & Regards
Ravikanth
