MySQL 5.6 slave Slave_IO_State is in system lock state
I’m seeing the same problem and I can replicate, I also only found the [COLOR=#252C2F] case but I don’t think I’m affected.
We run 5.6.12 in AWS’s RDS, it’s a big Magento (php) installation.
What’s interesting for me is that I see System Lock on the master as well. Can you double-check in your case and confirm? I suspect you’ll see it on the master as well.
I use monyog’s Real-Time feature and I’ve got 54% in System Lock…
Oh, needless to say, any help will be very much appreciated. I will keep you posted of my progress.
