I'd like to say Hello to the whole Forum

But cut to the chase:
Access Server version: 1.8.4
Authenticate users with: ldap
Accepting VPN client connections on IP address: all interfaces
Port for VPN client connections: tcp/443, udp/443
OSI Layer: 3 (routing/NAT)
Clients access private subnets using: NAT
Failover : enabled
Amount of users connected to the AS: ~350-500 concurrent
OVPN AS Nodes information:
Red Hat 5.9 (64bit)
Intel(R) Xeon(R) CPU X7560@2.27GHz (2 cores)
6G RAM
LDAP connectivity: LDAP Proxy (Windows 2k8R2) <=> DC (Windows 2k8R2) (First client installed on LDAP proxy need to connect with local account over internet, then LDAP traffic is routed via this link)
Recently I'm experiencing two different issues (they occur randomly)
1. Few weeks ago I had a problem with authentication. LDAP disconnects itself from OpenVPN - which causes unavailabilty of service - but moreover I wasn't able to logon using local account. Failover to second node solved the problem - but after a while I had similar issue. Can anyone of you experience anything like this?
Some logs regarding that issue:
