After importing a wallet in simplewallet, issuing the rescan_bc command consistently results in the following "Abort trap: 6" error on my computer:

[wallet 4*****]: rescan_bc
Starting refresh...
Abort trap: 6/ 1124452

The refresh command also fails:

[wallet 4*****]: refresh
Starting refresh...
Abort trap: 6/ 1124458

It happens around height 85000. What could be the reason for this, and how should one resolve it?


Run those commands, and put the result of "bt" on a new issue on https://github.com/monero-project/bitmonero:

ulimit -c unlimited  
gdb /path/to/bitmonerod core  # the core file migh thave a PID suffix, use it if so

This is unexpected, and will need fixing. Please include what OS/architecture you're on, and which version of bitmonerod you are using.

  • I had to install gdb first on my Mac, did so with brew. Running gdb /opt/monero/bitmonerod core prints a bunch of warnings about Could not open OSO archive file "/usr/local/lib/libboost_*.a" and then nothing. After simplewallet crashed with Abort trap: 6, I typed bt in gdb, which says No stack. I noticed this topic was discussed previously on Reddit.

    Ah, if on a mac, try running with --max-concurrency 1

    That didn't work for me. But rebuilding from the latest souce solved the problem (I used brew install bitmonero --HEAD -v for this). On Reddit the issue was referenced as issue #942. I am seeing my transactions now being found when scanning through the blockchain. The process seems to be much faster also in the latest code.

Upgrading to the newest 0.10.0 "Wolfram Warptangent" release solves for me the issue on OS X.
