Upon the load and subsequent install of policy from the remote URL the proxy “froze” while installing the policy. It remained otherwise operational, with the inability to install policy, stating a policy load was already in progress.
Using the group caching feature, which means other than the first time policy is loaded or when a new group is added to policy, lookups will not actually be done except once every 15 minutes for groups that haven’t been successfully looked up.
There is a read write lock that causes proxy to be in a "froze" state. The proxy simply never finishes installing policy and cannot start a new policy installation because the process is hung and requires a manual reboot to recover.
If the policy contains authentication groups in domains the SG cannot connect to (nonexistent groups), a kernel error may prevent the installation of the policy to complete on the SG. This has been resolved in 126.96.36.199 and later releases.
Issue fixed in SG version 188.8.131.52
