![]() and so onįor the CONCURRENCY_LIMITS, halve and increase by 50% until you get a value that works. If its OOM killed, increase the value by 50%. You may use a binary search technique to hone in on a value appropriate for a production pipeline:įor cache_size, max it out. STORAGE_PUT_FILE_CONCURRENCY_LIMIT limits the number of parallel downloads pachd will initiate.STORAGE_UPLOAD_CONCURRENCY_LIMIT limits the parallelism to put files into the storage backend.If it still gets OOM killed by k8s, there are a couple of environment variables you can set in your pachd deployment to limit the amount of memory the sidecar and pachd use. Increase it to what you can afford its default is 64M.(If you’re using a release prior to 1.10.0 and you have cluster-wide or namepace policies on resource limits, you may need to manually edit the pipeline RC.) You can give the storage container more resources by increasing the cache_size parameter in your pipeline spec. pachd or worker: all SubConns are in TransientFailure, latest connection error: connection error: desc = \"transport: Error while dialing dial tcp 127.0.0.1:653: connect: connection refused\" retrying in XXXX.XXXXXs"}Įither pachd or your pipeline’s worker sidecar may be getting OOM killed as it grows while getting data from object storage. ![]() pachctl errror: an error occurred forwarding XXXXX -> 650: error forwarding port 650.You may see log messages containing the following in either pipeline logs, pachd logs, or from the pachctl command locally: Failed Uploads # Symptom #Ī file upload, particularly a recursive one of many files, fails.

The default channel used to download packages is the anaconda channel, but the official anaconda package is somehow quite slow in terms of package updates. Use to resolve this and similar problems. Pachyderm supports standard bash utilities that you can Is treated as a command flag instead of a repository. Naming a Repo with an Unsupported Symbol # Symptom #Ī Pachyderm repo was accidentally named starting with a dash ( -) and the repository You’ll also want to make sure you’ve allowed ingress access through any firewalls to your k8s cluster. If you need to do large downloads/uploads you should consider using pachd address config value. If you do not explicitly set the pachd address config value, pachctl will default to using port forwarding, which throttles traffic to ~1MB/s.
