<@U037ZCHAX3P> are you running signoz using docker-compose or helm?

its a standalone setup with all containers running on an ec2 instance, collector is crashing frequently with the exception mentioned above and we are having to restart the containers

ok..use `dimensions_cache_size: 10000` at otel-collector-config <https://github.com/SigNoz/signoz/blob/develop/deploy/docker/clickhouse-setup/otel-collector-config.yaml#L27> like
```  signozspanmetrics/prometheus:
    metrics_exporter: prometheus
    latency_histogram_buckets: [100us, 1ms, 2ms, 6ms, 10ms, 50ms, 100ms, 250ms, 500ms, 1000ms, 1400ms, 2000ms, 5s, 10s, 20s, 40s, 60s ]
    dimensions_cache_size: 10000```
 and then restart otel-collector using
```sudo docker-compose -f ./docker/clickhouse-setup/docker-compose.yaml restart otel-collector```
this should fix the issue

okay let me try this, thanks for quick help

<@U02SS3ZAMKQ> please raise a PR with above as default config for docker-compose setup too. I see we have that in helm chart already

<@U037ZCHAX3P> let us know if this worked :slightly_smiling_face:
