Is filecoin main chain stable?

[jimzen]

Ran one month with lotus to sync with main chain, hit bad blocks every one or two days. It is insane.

Also tried to use daily snapshot to sync as well, and if is just luck to have one day synced without bad block.

No tricks or anything, just clean sync.

Here is the log from today:

It is really not clear to me why you are having this problem, there are many factors that could be the cause.
I replace my chain with the import command every few weeks without a problem.
Some issues we often see:

• Disk storing chain is too slow
• CPU is not up to the task (or not enough memory)
• Disk not large enough (chain grows about 40GB/day
• Network not fast enough
• Corrupt chain
• Hardware problems

After many fails using the code, I pulled the code and built again. Now it is stable after using the updated repo. Hope was not a fork.
