项目是用java写的，之前都运行正常，可以从server中读取数据，运行了一段时间后，报上面的错误，尝试过下面的解决方案
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
create or modify 32-bit DWORD: LocalAccountTokenFilterPolicy
set the value to: 1
还是报错，查了一下可能是DCOM的错误，也尝试了下面的解决方案
https://www.softwaretoolbox.com/dcom/html/configuring__opcenum1.html
还是报上面的错
请教一下，如何解决？谢谢
补充：
调试发现，是j-interop调用WMI链接失败，还是不知道如何解决
这段话
Access is denied, please check whether the [domain-username-password] are correct
的意思是：访问被拒绝，请检查域账户密码是否正确
你看一下是不是程序使用了域账户，密码是否过期或被修改了
你这个是dcom不是com，是进程外的，首先需要检查opc服务器的进程是否挂了，重新启动下计算机
如果要是经常不稳定，你需要首先检查有没有干扰它运行的某些程序，比如杀毒软件什么的，还有就是opc服务器本身的问题，可以查看日志或者和厂商联系咨询。

请问这个是opcServer 端的内存不足吗？应该怎么解决
