Intermittent RPM Sync Failures When Using NFS-Mounted Storage With Parallel Syncs

I’m deploying the Pulp container (pulp/pulp:3.80) and mounting an external NFS share inside the container. I’ve enabled parallelism during pulp sync and am syncing large RPM repositories (e.g., EPEL). During this process, I’m seeing intermittent sync failures for some RPMs, with errors like:

Failed during synchronization of RPM repository for: x86_64_appstream, x86_64_baseos, x86_64_codeready-builder, x86_64_epel, aarch64_epel

I want to understand whether the read/write performance of the NFS share can cause sync failures. Specifically, when multiple syncs run concurrently, can slow NFS I/O lead to sync failures?

Also, is there a Pulp command to see more detailed logs for the pulp rpm repository sync command— something like a verbose/debug mode?
