LLR v 3.8.13 does the same.

oMaxrestarts=20 Increase it to 40, this could be enough.

Re: 1024*3^1877301+1, which was discussed in http://primes.utm.edu/primes/page.ph...18946#comments  this is prime, and LLR 3.8.16 confirms it is prime. The uncertainty was due to a bug in gwnum which was fixed in the previous release.  Iain

It reminds me to ping Chris who was waiting for the software to mature to replace his UTM server side LLR and PFGW and then trigger the standard reprocessing and have the 'External' tag removed. I'll email him that LLR 3.8.16 is what he wants to use from now on. As well as the latest PFGW.

I have found some errors in results:
Number sent to gwsetup is too large for the FFTs to handle. Happened on a GenuineIntel Intel(R) Celeron(R) D CPU 3.46GHz [Family 15 Model 6 Stepping 5] After 5 sec it has finished the WU.

Updated Win64 binaries now uploaded
Hi,
Thanks to Rebirther, the two Win64 binaries are now also updated accordingly to the minor change I made on the 06/08/15. Regards, Jean
