Multichaind segfaults with bitcoin config

Fri, 07 Apr 2017 11:25:53 +0000

Hello,

I compiled multichain on ubuntu 16.04. Multichaind runs ok with default params generated by multichain-util, but when i use params.dat from http://www.multichain.com/download/bitcoin-protocol-params.dat I get immediate segfault.

Stacktrace from gdb shows:

Program terminated with signal SIGSEGV, Segmentation fault.

Any ideas how to approach that problem?

Is MultiChain current build prepared to process a large amount of transactions?

Im testing MultiChain and I will be using it on a public entity on my country as a TimeStamp service.

Today I got this:

Aug 22 15:54:41 multichain-test kernel: [743058.944750] multichaind[24556]: segfault at 0 ip 000000000066e077 sp 00007fb7e0cf8390 error 4 in multichaind[400000+7ed000]

I wonder if you would recommend the current build (1.0-alpha-23) for this usage or if maybe its too unstable to use in production.

Thank you very much
