Hi, I am copying the logs snippet of nova-compute.log from controller node. The issue i noticed is horizon page doesnt load properly and sometimes takes longer time open the page or never opens. Also when i try "openstack image list" or nova list or any other openstack cmds, it takes very longer time to show me the - ClientException error. As a workaround i restart my openstack using "systemctl restart openstack-*" and seems like everyting works fine for few minutes and issue occurs again after sometime and it repeats.
Please do let me know if there is permanent workaround or something to reconfigure?
