.SH DESCRIPTION
.sp
\fBtraffic_cop\fP is a watchdog program that is responsible
for starting \fItraffic_manager\fP and \fItraffic_server\fP
and monitoring them for responsiveness. If either of these processes
are determined to be unresponsive, \fBtraffic_cop\fP will kill
and restart them.
.sp
On Linux, \fBtraffic_cop\fP will also monitor available memory
and swap space, restarting the watched processes if the available
memory falls below a minimum threshold. The memory thresholds can
be configured with the \fBproxy.config.cop.linux_min_swapfree_kb\fP
and \fBproxy.config.cop.linux_min_memfree_kb\fP variables.
