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 utility is not active in system memory. The instructions in this section
guide you through the steps to terminate polling associated with the dhctStatus
utility and to remove the signonCount utility from system memory.
