The first time, I was able to log in via remotely, saw a ton of spam apparently abusing a php mail form script (more on that later) filling the /var partition. I purged it, but it still required a reboot as CPU was through the roof. Yesterday morning, I was unable to get into the server at all...pings were very high. I called the provider and got in via KVM over IP. CPU was fine and there wre no full partitions. As I had to catch a flight, I just rebooted it and it was fine. After getting home, I looked in the syslog and see thousands of these: Jan 26 21:50:32 host named[667]: client #57938: error sending response: not enough free resources Jan 26 21:50:32 host named[667]: client #59830: error sending response: not enough free resources Some googling on this error found a reference to a possible queue limiting problem in pf/qlimit, but the only firewalling I do is a very basic ipfw setup strictly for bruteblock. I am not even sure if this error caused the outage(s) or was caused by them, let alone a fix or workaround. Appreciate any and all clues, especially if you are familiar with this. TIA!
