Description

A customer had an S3 blobstore configured for their helm repositories:

Only requests related to helm repositories were causing failures, other repo formats with their own blobstore were not experiencing problems.

There is a leak of either HTTP connections for S3 / Azure blobstores, or file handles for File based blobstores.

Example for S3 blobstore:

Expected

Do not leak S3 blobstore connections or file handles for Helm Repositories.

Workaround

To clear the leak, a restart of Nexus Repository is required.

If the leak surfaces after a long period of time, then more frequent restarts might help avoid the issue, along with increasing the S3 default connection pool size.

Until the problem is fixed, then not using S3 blobstores for Helm format repositories might be preferred.
