#381 SSSD can't handle a DNS timeout
Closed: Fixed Opened by mnagy.

Closed: Fixed
Reopen Issue

When the DNS server doesn't respond, SSSD will get stuck. From the logs:

(Mon Jan 11 14:28:08 2010) [sssd[be[LDAP]]] [fo_resolve_service_send] (4): Trying to resolve service 'LDAP'
(Mon Jan 11 14:28:08 2010) [sssd[be[LDAP]]] [get_server_status] (7): Status of server 'nonexisting.address.dfjofisja.com' is 'name not resolved'
(Mon Jan 11 14:28:08 2010) [sssd[be[LDAP]]] [get_port_status] (7): Port status of port 389 for server 'nonexisting.address.dfjofisja.com' is 'neutral'
(Mon Jan 11 14:28:08 2010) [sssd[be[LDAP]]] [get_server_status] (7): Status of server 'nonexisting.address.dfjofisja.com' is 'name not resolved'
(Mon Jan 11 14:28:08 2010) [sssd[be[LDAP]]] [resolv_gethostbyname_send] (4): Trying to resolve A record of 'nonexisting.address.dfjofisja.com'
(Mon Jan 11 14:28:08 2010) [sssd[be[LDAP]]] [set_server_common_status] (4): Marking server 'nonexisting.address.dfjofisja.com' as 'resolving name'

This is caused by the fact that the async resolver only calls c-ares processing function when there is an activity on a file descriptor used by c-ares. If there is a timeout, however, the function is never called, since there is no activity on the FD.
