I run a C8 and I upgraded to 2.5.1.183 recently and Helog that has been running forever would stop within 15 minutes. The only thing that would get it going again was Rebooting Hubitat. I have another program that uses Log Socket to do the same kind of thing that Helog does and had similiar problems. Another problem I had was getting a "java.lang.NoClassDefFoundError: com/hubitat/hub/executor/SandboxSubscriptGuard on line 560 (method illuminanceHandler)" in one of my custom apps that has been running without change for at least a year. BOTH PROBLEMS WENT AWAY WHEN I DOWN GRADED TO 2.5.1.152.
If this error is from a community maintained app/driver you should post details in that community thread so the developer or users can help you.
If it is something you wrote more details about the app/driver will be required for community members to help you.
