We've been stopping both DS instances (main and PKI) when upgrading. This can happen while the CA is running. In some cases stopping the PKI DS also killed the CA. Only stop the specific instance for upgrades. Also, wait for open ports after the upgrade is complete. The wait was skipped previously. This can prevent bugs if scripts that need a DS are run after the upgrade. https://fedorahosted.org/freeipa/ticket/3083
