Congrats to Curtis Cooper for a huge prime 21*2^1830919+1, 551163 digits! Currently ranked 16th largest. According to the page below he is using PRP, and...
The October 10 I sent the sequence A098845 to OEIS primes of the form 2^k*(2^k-1)-1 until A098845(33)=14610 Now I found A098845(34)=43401 and A098845(35)=45306...

Most likely these are false alarms. What version of LLR are you using? It happened before on some k/n pairs when using LLR released in April this year (2004)...
Thanks again, Predrag. I checked the LLRP43 residues that followed the error messages, using LLR21, and got the same ones. So they do seem to be false alarms....
