out-of-sync in Gridcoin 3.5.8.8 ?

We've noticed a new problem in the last 12h with Gridcoin 3.5.8.8,

    a few people had again out-of-sync problems (means: they wouldn't get new blocks).

What helped them was:

1. a restart of the Gridcoin client.
2. at restart your client may still show the mandatory block 860500 for a few minutes, but should show the higher block amount soon then. So, make sure you wait for like 5-10 mins (on slower machines, wait a little longer).
3. verify your block hash with: 

• a. users in our IRC channel, or 
• b. see the block hashes posted regularly on twitter: @GridcoinIRC
• c. I will post hashes regularly also in the comment section below
• 
  
• Currently, the block 861523 has the hash: 5­0­6­f­9­9­c­1­c­d­e­a­2­b­b­c­b­f­1­e­7­b­3­a­0­3­9­9­e­e­b­1­9­a­a­8­5­5­1­3­c­3­e­f­3­2­c­6­6­b­9­1­4­3­8­1­7­3­4­a­1­d­2­f (see A) )

How do you know something is wrong ?

• your "PoR Difficulty" in the client is very low, e.g. <1 values (e.g. 0.4)
• you stake too fast blocks

Our devs are investigating this issue currently (see e.g. bugtracker for updates).

In case the above steps did NOT help you, come to our IRC channel.
