hey, i use pulsar based on version 2.6.0
once broker had an oom problem and soon shut down, after we restart the
broker, we find our apps can not connect pulsar, it said:
```
[persistent://xxxxxx_fun/menu/xxxxxx-recombination-topic-partition-0] [null]
Error connecting to broker:
org.apache.pulsar.client.api.PulsarClientException$TimeoutException: 74 lookup
request timedout after ms 3001
```
then we check with command "pulsar-admin topics list" and found that some
topics can not display which return 500 internal error but the othders worked.
the log show :
```
16:42:12.605 [pulsar-web-42-8] ERROR
org.apache.pulsar.broker.web.PulsarWebResource - **Finding owner for topic
persistent://xxxxxx_test/menu/xxxxxx-systemOperLog-topic-partition-0 timed out**
