Hi
I have a serious problem.

I have a zimbra multi server(2 ldaps, 2 mtas, 1 mailbox) for 7000 accounts and now the server is really slow.

I'm watching the process of the cpu and slapd is overloaded. I'm looking the connections of the ldap's servers

This output of the netstat of the ldap0

The output of the netstat of the ldap1 is:

Code:
tcp        0      0 zldap1:47966                zldap0:ldap                ESTABLISHED 9845/slapd 

tcp        0      0 zldap1:ldap                 *:*                         LISTEN      9845/slapd

Any body know where can I find the problem???

Its very strange

Best regards, thanks
