Known Affected Releases

3.6.3.BASE

Description (partial)

Symptom:
 After a system reload, OSPF neighbors/adjacencies can take an extended period
 of time to establish. During this time, OSPF commands are unresponsive. An
 error message similar to the example below may be observed:
 
 RP/0/RP0/CPU0: sysdb_svr_shared[555]: %SYSDB-SYSDB-7-TIMEOUT : EDM request for
 'oper/ipv4-ospf/gl/proc/100/vrf/default/public/xml/process/area_proc_terse/'
 from 'ospf_show' (jid 65798, node 0/RP0/CPU0). No response from 'ospf' (jid
 426, node 3/RP0/CPU0) within the timeout period (100 seconds).
 
 Conditions:
 
 Condition can be observed under specific circumstances, 1) Multi- chassis
 system running IOS-XR release 3.6.3 without SNMP configuration, 2) Single chassis system DRP/B(s) 
for process
 distribution (manual or automatic (note that manual process distribution is not
 formally supported)), 3) When using Secure Domain Routers (SDR) with a DRP/B
 hosting the SDR function.  In all of the instances above there must be no SNMP
 configuration present for this problem to occur. ISIS is not affected by this issue.
