Stop the dhctStatus, signonCount, and cmd2000
Processes
When sites are being upgraded, the dhctStatus utility may occasionally be in the
process of polling DHCTs. Additionally, the signonCount utility may be active in
system memory. Our engineers have discovered that upgrades proceed more
smoothly when the dhctStatus utility is not actively polling DHCTs and when the
signonCount and cmd2000 processes are not active in system memory. The
instructions in this chapter guide you through the steps required to stop these
processes.
