### Problem Description

We see 8.6.0 master nodes (512MB heap) repeatedly dying with OOME when attempting to do a snapshot with GCS snapshot repository. This is not reproducible with prior versions and we suspect that this is caused by https://github.com/elastic/elasticsearch/pull/90282.

### Steps to Reproduce

1. Start a cluster in a containerized environment; master nodes have 1GB of memory, 512MB of heap
2. Setup a GCS snapshot repository
3. Create a snapshot of the cluster.
4. The master node will OOM with the following message:

```
[5383.050s][warning][gc,alloc] elasticsearch[i6][snapshot][T#26]: Retried waiting for GCLocker too often allocating 256 words
[5383.053s][warning][gc,alloc] elasticsearch[i6][snapshot][T#14]: Retried waiting for GCLocker too often allocating 1029 words
java.lang.OutOfMemoryError: Java heap space
```
