This is what I get in the system log when things go down:
Which led me to believe it was a DNS issue. However, when I try to ping an IP address like Google's 8.8.8.8, I get this:
After a bit of research, it seems like I might be having memory issues, but [CMD="netstat -m"][/CMD] returns:
I'm no BSD expert, but that doesn't look like I'm having a memory problem. So, any ideas what might be causing this drop in the connection?
