This is freaky. I use Big Sister to monitor my networks. Earlier today, I began getting CPU utilization messages on two of my proxies. Each proxy was reporting 99 percent utilization, caused by the squid process. These = proxies are located at completely different businesses located on opposite ends = of town, and they have no affiliation with each other.
I investigated for a few hours and I couldn't find a reason. The access logs weren't excessive and there didn't seem to be a lot of = traffic through the proxies. Then I looked at my big sister trend logs and really freaked out. They = both started spiking at almost EXACTLY the same time and in EXACTLY the same = pattern. To see what I mean, check out the patterns: http://www.corn-bread.org/admintest.bmp http://www.corn-bread.org/rudolph.bmp Note that the times, severity of the spike, etc are roughly the same. Both systems are redhat 9 running squid rpms (squid-2.5.STABLE1-3.9). I can post my squid.confs if needed. Any known issues right now? Thanks. Scott.
