The select(2) system call changes introduced with PHKL_41700 patch causes issues with timer functionality that HAD daemon uses.


This issue is fixed by HP via PHKL_41967 patch. We suggest to install this patch, which requires system reboot.


Until the patch can be installed, below workaround can be used, that does not require reboot.

1. Enable high resolution timer functionality.

# kctune hires_timeout_enable=1

2. Restart HAD daemon

# hastart
