Constant "remote cache eviction error" message

[BalestraPatrick]

Description of the bug:

Hello!

We've been using the various flags related to addressing remote cache evictions in multiple projects successfully. I noticed an interesting behavior in one of our repos lately after taking a closer look at our CI logs. We consistently see the same action/invocation failing with a remote cache eviction error and then recovering by itself.

We run the bazel-diff tool in a bazel run invocation, which always fails with the same missing digest bazel-out/k8-fastbuild/bin/external/rules_java/toolchains/platformclasspath.jar. When I query the remote cache for that particular digest using tools_remote, I get the correct blob returned. This means that the blob is in our remote cache, but somehow Bazel thinks it's not? I have an execution log for the specific situation as well if needed. I attached the part of the log where I could find two instances of this particular digest.

Which category does this issue belong to?

Remote Execution

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

I wasn't able to reproduce this easily just yet, but it definitely requires a remote cache with the following flags enabled:

common --experimental_remote_cache_compression
common --experimental_remote_cache_eviction_retries=1
common --experimental_remote_cache_lease_extension

The rule that always fails is also pretty straightforward:

load("@rules_java//java:defs.bzl", "java_binary")

java_binary(
    name = "bazel_diff",
    main_class = "com.bazel_diff.Main",
    runtime_deps = ["@bazel_diff//jar"],
)

And the invocation looks like this:

bazel_diff=$(mktemp)
bazel run //tools/bazel_diff --script_path="$bazel_diff"

Which operating system are you running Bazel on?

Linux

What is the output of bazel info release?
