A bluescreen crashed the server. The good thing, the database survived, In logfile found system_service_exception ntoskrnl.exe 0x0000003b and ran a chkdsk and sfc /scannow, something was repaired with chkdsk.

The bad thing, I dont know exactly whats causing this problem, driver or SSD.

More infos ntoskrnl.exe+3f70d0

The app divides the number 607920 / 51 = 11920. The gwnum lib has a bug somewhere and the dev is informed.

At the moment only S51 is affected.

Base S51 will be stopped for the time being after 35-37k is done, the tests are correct with the divided numbers but primes cant be removed from the sievefile.

All affected tests must be convert to the correct values. This takes time.

Within the infrastructure problems are the needs for mass data storage.

We need an LTO drive or LTO library.
Alternatively, LTO tapes themselves may also be useful.

The preferred LTO generation is LTO4 or LTO5.

If anyone has any in their storeroom/basement/garage :) we are happy to accept this type of equipment for our own needs.

Perhaps it is just taking up unnecessary space at someone's place.

If anyone knows anything about this type of equipment, please send us an e-mail:
