我在嵌入式模式下使用 Infinispan 9.4.16。这是缓存的配置：
<distributed-cache name="mycache" mode="SYNC" remote-timeout="15000" l1-lifespan="60000" owners="1" segments="80">
<locking striping="false" concurrency-level="100" acquire-timeout="60000"/>
<persistence>
...
</persistence>
<state-transfer chunk-size="512" timeout="240000"/>
</distributed-cache>
我运行一个由 4 个节点组成的集群。可以同时读取、更新或删除此缓存中的条目。所以随机地，一个线程被这个堆栈跟踪阻塞（无限期地等待）：

经过一番调查，我发现线程被自己阻塞了。但我不知道这怎么可能。这是 Infinispan 的问题吗？
