restoring dumpfiles

[ingvar_e]

I have some dumpfiles. from 4 bitcoin installation on my W1ndows 10 desktop. I am running the latest version. The dumpfiles  where created with the previous version-

when running the command "importwallet" I get 2 different responces.

"null"  which I interpret as  OK

"Error: std::bad_alloc"  which I do not understand.

I have checked the input files and they  look ok

Suggestions?

From some old threads I found it was suggested that the 'bad_alloc' error suggests low ram memory. Now I am not sure if this is the case here as well.
How much RAM do you have and are you using a 32-bit or 64-bit version of Windows?

I am running Windows 64 and I have 12 GB of memory

As Pmalek pointed out, there have been similar topic on this issue sometime back. When the Core has ran out of virtual memory I guess this issue pops up. Core uses above the normal memory to access and run the application. Just edit the .config file of Bitcoin Core and add

-dbcache= a value lesser than allocated RAM

If this doesn't solve your problem try to edit the config file and type

 -maxmempool=value less than 300

These should have lesser ram usage than your current scenario. There are other ways to reduce the RAM usage. Check this out : reduce-memory
