Do these messages still pop up and can you list the names of the characters you've had cause it and roughly the time it occurred?
Also, what messages did you received when logging in other than seeing the cmd_pc_update error?
The messages and lockdowns don't seem to be happening any longer, but they did start a few days ago, stop after a reset, then start again a few resets later.
Times and characters seemed to be random, I couldn't figure out anything matching them, but they were happening quite quickly at high traffic times. Alandor 'Nazusin, Perdiot Olivene, Mixtli Darkcloud, Rand Browning, quite a few others I don't think I can remember, there were probably about 20 over two days there.
The cmd_pc_update errors were the only message people were telling me about, the only thing changing between them was the fffffXXX.
