cli_wallet keeps crashing

[roadscape]

Last night I had to update and rebuild the node on the cryptofresh server. The witness_node and cli_wallet had been running smoothly for weeks, but now cli_wallet crashes randomly, on average maybe every 5-15 minutes.

I was getting a different error last night, one that didn't crash cli_wallet, but made it forget how to perform a 'get_object' call. I didn't save that one unfortunately. This morning, I am seeing a more cryptic error:

Code: [Select]

When this happens, I restart the cli_wallet, and everything works fine for another 5-10 minutes.

This is a big PITA for cryptofresh.com.. I'm at my wits end with this issue... any help/leads are appreciated.

I've tried the following to no avail:
 - starting with a new wallet
 - building 'bitshares' latest
 - building 2.0.160302 (failed)
 - building 2.0.160309
