我们有一个大约 11 个节点的 Percona Xtradb 集群。其中一个节点在大约 2 天前崩溃了，但现在即使在捐助者指示 SST 过程已完成并且该节点现在已加入集群之后也无法再次启动。
当我检查无法启动的崩溃节点的日志时，我不断重复看到此错误（以小时为间隔）：
[Warning] WSREP: Failed to report last committed [xxxxxx] -4 (Interrupted
system call)
但在此消息在几个小时后在错误日志中弹出一次之前和之后，唯一记录的行是：

什么可能导致这种情况发生？为什么这个节点不会重新启动？以及如何修复节点、启动它并让它再次加入集群？
