To answer your question about the proxy connection, every 60 seconds I get one of these in the /var/log/messages file on the VMware server when the VEEAM services are started.
May 20 18:25:43 Hostd: [2011-05-20 18:25:43.787 5ECDBB90 verbose 'Proxysvc Req00000'] New proxy client SSL(TCP(local=192.168.1.142:49897, peer=192.168.1.202:443))
According to VMware, when the VMware server boots it sets the max proxy connections to 320 (see the log entry below). When this is reached, the server stops responding to certain requests like client connections. The VM's and the host continue to run normally, but in order to be able to regain hosts connections you have to ssh to the server and run the "/sbin/services.sh restart command". The only way to reset the proxy connections is to reboot the VMware host. There is also no way to increase the settings to something greater then 320.

Here are the steps I took to debug.
- Stopped the VEEAM Data Collector Service, and the SQL Server (VEEAM) on my machine
- Ran the "/sbin/services.sh restart command" on the VMware hosts
- Tested connectivity to VMware, and it worked fine
- Rebooted my machine and let the VEEAM services start
- After a few minutes VMware connectivity went away
- Stopped and disabled the VEEAM services
- Rebooted my machine and the problem has not come back
