租户-1234的部署同步提交失败WSO2 IS 5.0.0

我正在运行WSO2 IS 5.0.0 . 我已经为IS 5.0.0应用了SP以及为该版本为Identity Server和Carbon 4.2.0发布的所有其他安全补丁 . 我的环境由4台创建集群的计算机组成（使用WKA成员资格方案和Load Balancer（AWS ELB）并启用了粘性会话） . 我正在使用MySQL（不是默认的H2数据库） . 部署IS的计算机是Windows Server 2012 R2（EC2 AWS计算机） .
我经常在控制台日志文件"Deployment synchronization commit for tenant -1234 failed"中收到 . 在我应用@ycr建议的更改后，为了禁用Dep-Sync：

<DeploymentSynchronizer>
<Enabled>false</Enabled>
<AutoCommit>false</AutoCommit>
<AutoCheckout>false</AutoCheckout>
<RepositoryType>svn</RepositoryType>
<SvnUrl>http://svnrepo.example.com/repos/</SvnUrl>
<SvnUser>username</SvnUser>
<SvnPassword>password</SvnPassword>
<SvnUrlAppendTenantId>false</SvnUrlAppendTenantId>

并重新启动我的所有机器 . 大约两周我没有问题 . 然后突然我收到了同样的错误，但今天我的两台机器上有额外的堆栈跟踪（29.09.2016）：

我需要调整任何其他配置文件吗？
