Node crashes during RPC connection calls.

Question

I have a node running where there are a lot of RPC connection calls.  Connections accessing the wallet for various purposes.  The problem is the node crashes constantly and I have to start the node again.  It seems like the crashes are being caused by the RPC calls.  Its an intermittant problem because sometimes it runs fine then other times right after and RPC call it goes down.  At one point it left a lock file in one of the folders and I had to remove the lock file and reindex the entire nodea again to get it working.  Not sure why the node is running so unstable.  I have other nodes connected who are just mining with no RPC connections and they seem to stay up.

Thanks for reporting this. Here's how we can help resolve it:

1. Stop the node which is crashing
2. Re-run multichaind with the extra flags: -debug=mchn -debug=mcapi
3. After a few crashes, zip up the blockchain directory and send it to us at multichain.debug@gmail.com – we will then take a look.

I zipped up the node and posted it to a location we used in the past to debug some nodes.
