Error when checking the wallet history: ValueError: f(a) and f(b) must have different signs

[GerdOpp]

When I want to check the wallet history, either using JoininBox or "python wallet-tool.py walletName.jmdat history" I get the below error. However, the display of the TXs is correct.

I had an issue with the tumbler before where the min cj amount of 1.000.000 seems to be too high and the process aborts with: "Unable to select sufficient coins: NotEnoughFundsException"

Then the tumbler did not work and always hangs with: "DEBUG:Failed to get wallet information, is there a problem with the blockchain interface?"

I don't know if these errors are connected.

Thanks for looking into it.

I first tried a Reboot of the RaspiBlitz: no change Then today a complete PowerOff: After this it worked ok

I re-open this issue because I really would like to know what has happened there and if it was a fault on my side (which?). I am a little afraid to use the tumbler again.

I get the same error again with a different wallet while the history itself seems ok.

Could it be just a failing hardware issue?

I don't know. My node (RaspiBlitz) is working now for several months without any problems.

I have several wallets and I can get the history from all of them but this one. With this wallet the above error message is reproducible if I want to get the history. For a test, I just powered-off my node but the error is still present.

There is one commonality. In both cases, the wallets were used for a Tumbler action with JoinMarket-Qt and the process aborted with the error "Unable to select sufficient coins: NotEnoughFundsException".

Maybe this information helps?
