You will notice a vast majority of pools have issues.   And the reason this is that while the pool software is open source, is excellent, and it is an amazing contribution it is not perfect. Much like many open source projects.  In fact, there is many commits everyday to the system, on github, to fix issues and problems in the software.

The point of this is that pool owners are dealing with a complicated system to setup, and maintain.   If it was easy to do then more would do it.  But it's not, and things break.
