Finally traced this to the 389-ds-base-1.3.7.5-24.el7_5.x86_6 update. It would cause our IPA ldap server to hang, which would hang autofs when trying to lookup ldap map entries. I've filed https://pagure.io/389-ds-base/issue/49815 and have now downgraded. Hopefully that will take care of it. -- Orion Poplawski Manager of NWRA Technical Systems 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane or...@nwra.com Boulder, CO 80301 https://www.nwra.com/
