xiemeilong opened a new issue #9213:
URL: https://github.com/apache/pulsar/issues/9213
**Describe the bug**
I install pulsar on kubernetes using official helm chart . All my connector
can not created successfully, even the builtin( for example debezium-mysql ).
I found the OutOfDirectMemoryError of direct memory in the log of broker.
But the exception still exists after increate direct memory from 256MB to 2GB.
But the connector runs in local mode normally.
**To Reproduce**
1. helm upgrade --install pulsar apache/pulsar --timeout 10m --set
initialize=true
2
```
bin/pulsar-admin source create --tenant iot --namespace pipe \
--name xxxxx --destination-topic-name xxx/xxx/xxx --parallelism 1 --archive
builtin://debezium-mysql \
--source-config '{ "database.hostname": "mysql", "database.port": "3306",
"database.user": "xxxx", "database.password": "xxxxx","database.server.id":
"1","database.server.name": "xxxxx","database.whitelist": "xxxx",
"table.whitelist": "xxxxxx","schemas.enable":false,"pulsar.service.url":
"pulsar://pulsar-proxy:6650" }'
```
3. the broker log
```
