This is a difficulty problem from the pools.
Example:
If dif. of 512 is fed to all my 5 gridseeds, they die. If dif. of 67 diff is fed to them all five, they stay alive.
You guys need to talk with the pool owners.
It's not minera.
Pooler just added difficulty change to his pool. litecoinpool.org. If you have a blade and an account at litecoinpool.org.
This is how you set the dif.
I have implemented a basic way to manually set a fixed difficulty per connection, and I would like you to try it out.
This is currently only supported by one of the two servers that we have on the East Coast, so you will need to connect to us3.litecoinpool.org to perform the test. (I will later deploy the change to all servers if testing goes well.)
To set a fixed difficulty N, just add ",d=N" to your worker's password when you connect. For example, if the password is "foo", connect with password "foo,d=64" to get difficulty 64.
Looking forward to your feedback,
My gridseeds now do not die on litecoinpool.org.
You guys are gonna have to talk with clevermining admin Terk to implement difficulty settings and use lower dif settings.
Edit:
Another place to test is maniacminer.in. You can change diff. on your workers.
Mhh i don't have a problem with high difficulties. the blades are running fine. i´m at difficulty over 6000 now.
For me its just a question of how to calculate when a device is dead and if you do this based on the last mining results, it´s flexible for all difficulties.
