Hi all,

a) Log

I am getting this entries every 2 min in the /var/log/zmd-messages.log on each of my systems:

This means that every 2 min is trying to refresh the agent?There is any way to change this interval?

b) Performance

Running top |grep zmd command i get this output :

3511 root 34 19 111m 41m 9.9m R 30 11.7 0:10.64 zmd
3511 root 34 19 111m 43m 9.9m S 32 12.3 0:11.59 zmd

3511 root 34 19 121m 49m 9.9m S 1 13.8 0:15.50 zmd
3511 root 34 19 122m 51m 9.9m S 62 14.5 0:17.41 zmd



We are having some performance issues in the past few days and for me it looks like sometimes zmd is using a lot of memory and CPU.
Maybe changing the refreshing interval could solve the issue?

Many thanks
