Crashing on certain reorgs #192

Closed aivve closed 2 years ago

aivve commented 2 years ago

At some reorgs the daemon crashes with: malloc(): unsorted double linked list corrupted karbowanecd[3372]: segfault at 0 ip (null) sp 000000002d8f23a8 error 14 in karbowanecd[400000+34b000]

This seems to happen when a competing chain overcomes the node's chain.

The log from daemon:

Possibly #172 has something in common

Image 14 So it seems to be fixed now by #193
