如何修复“15 秒后无法获取锁"Wildfly 中的错误 [英] How to fix "Unable to acquire lock after 15 seconds" errors in Wildfly
本文介绍了如何修复“15 秒后无法获取锁"Wildfly 中的错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个 <distributable/> 的 Web 应用程序，但也部署到 Wildfly 的独立实例以进行本地开发工作.有时我们对后端的调用可能会停止几秒钟，这通常会导致如下所示的异常.
I have a web application that is <distributable/>, but also deployed to stand alone instances of Wildfly for local development work. Sometimes we have calls to the backend that can stall for a few seconds, which often leads to exceptions like the one shown below.
鉴于我无法控制长时间运行的后端请求，我该如何解决这个问题?
How can I fix this given that I have no control over long running backend requests?

推荐答案
我相信答案是像这样更新 infinispan 配置，将锁定超时增加到 60 秒.
I believe the answer is to update the infinispan configuration like this, which increases the lock timeout to 60 seconds.
<cache-container name="web" default-cache="passivation" module="org.wildfly.clustering.web.infinispan">
<local-cache name="passivation">
<locking isolation="REPEATABLE_READ" striping="false" acquire-timeout="60000"/>
<transaction mode="BATCH"/>
<file-store passivation="true" purge="false"/>
</local-cache>
<local-cache name="persistent">
<locking isolation="REPEATABLE_READ" striping="false" acquire-timeout="60000"/>
<transaction mode="BATCH"/>
<file-store passivation="false" purge="false"/>
</local-cache>
</cache-container>
