Right now, the server is not doing anything but sitting there....
Tasks: 98 total, 1 running, 97 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.0%us, 0.3%sy, 0.0%ni, 99.7%id, 0.0%wa, 0.0%hi, 0.0%si,
0.0%st
Mem: 1033780k total, 217560k used, 816220k free, 6220k buffers
Swap: 2019320k total, 0k used, 2019320k free, 94056k cached
Plenty of swap, not very busy. It may be over heating, but not sure why.
I am going to run a test tonight - ping every 10 seconds and time stamp the
output into a file. Perhaps I will see gaps or unusually long response
times and I can correlate that with the log files.
