Timeouts during ESXi conversion

[yaroslav (staff)]

Timeouts can be addressed this way:

1. Connected to ESXi via SSH using:
```bash
ssh -o PreferredAuthentications=keyboard-interactive root@x.x.x.x
```

2. Modified TCP keepalive settings in `/etc/vmware/rhttpproxy/config.xml`:
- Changed idleTimeSec from 900 (15 mins) to higher value (e.g., 28800 for 8 hours)
- This affects both serverSocket and clientSocket settings

3. Restarted services to apply changes:
```bash
/etc/init.d/rhttpproxy restart
/etc/init.d/hostd restart
```
