我有一个<distributable/>的Web应用程序，但也部署到Wildfly的独立实例，用于本地开发工作。有时我们会调用可能会停滞几秒钟的后端，这通常会导致如下所示的异常。
如果我无法控制长时间运行的后端请求，我该如何解决？

我认为答案是更新这样的infinispan配置，这会将锁定超时时间增加到60秒。
<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>

对于一个独立的我有同样的错误
我正在使用这个：
<cache-container name="web" default-cache="dist" module="org.wildfly.clustering.web.infinispan">
<transport lock-timeout="60000"/>
<distributed-cache name="dist" mode="ASYNC" l1-lifespan="0" owners="2"> <!-- IN 7.1+ REMOVE mode="..." IF PRESENT -->
<locking isolation="REPEATABLE_READ"/> <!-- REMOVE THIS LINE -->
<transaction mode="BATCH"/> <!-- REMOVE THIS LINE -->
<file-store/>
</distributed-cache>
</cache-container>
但改为：
<cache-container name="web" default-cache="passivation" module="org.wildfly.clustering.web.infinispan">
<local-cache name="passivation">
<file-store passivation="true" purge="false"/>
</local-cache>
<local-cache name="persistent">
<file-store passivation="false" purge="false"/>
</local-cache>
</cache-container>
然后就成功了。
