9 hubs, 5 C4, 4 C7.
All hubmesh'ed together.
Updated to 188.8.131.52 in hopes of curing severe loads and reboots.
2 C4 did not respond well, 500 errors and corrupted database.
Moved the problimatic hubs back to 184.108.40.206, they had been running well.
Restored database to the backup taken at last upgrade.
These 2 are doing the same thing, 500 errors and corrupt database, even having rolled back.
