Description Alexander Greene 2022-02-15 19:53:08 UTC
This bug was initially created as a copy of Bug #2003164

I am copying this bug because: 

It needs to be backported to 4.8.

### Description of problem

The olm pod was restarted and it's possible to see in the logs, the next error:

$ oc logs <olm operator> -p > olm_logs
fatal error: concurrent map writes

Comment 2 Jian Zhang 2022-03-17 06:41:54 UTC
1, Install a cluster with the fixed PR via the cluster-bot
mac:~ jianzhang$ oc get clusterversion
NAME      VERSION                                                  AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.9.0-0.ci.test-2022-03-17-055113-ci-ln-44p0tlk-latest   True        False         5m6s    Cluster version is 4.9.0-0.ci.test-2022-03-17-055113-ci-ln-44p0tlk-latest

2, Subscribe to some operators.
mac:~ jianzhang$ oc get sub -A
NAMESPACE             NAME          PACKAGE       SOURCE                CHANNEL
default               etcd          etcd          community-operators   singlenamespace-alpha
openshift-operators   amq-streams   amq-streams   redhat-operators      stable

mac:~ jianzhang$ oc get csv -n default
NAME                  DISPLAY                             VERSION   REPLACES              PHASE
amqstreams.v2.0.1-1   Red Hat Integration - AMQ Streams   2.0.1-1   amqstreams.v2.0.1-0   Succeeded
etcdoperator.v0.9.4   etcd                                0.9.4     etcdoperator.v0.9.2   Succeeded

3, Check the olm-operator logs.
mac:~ jianzhang$ oc logs deployment/olm-operator -n openshift-operator-lifecycle-manager|grep "fatal error"
mac:~ jianzhang$ 

Not found the `fatal error`, LGTM, verify it.
