Any idea why okcash wallets likes to go out of sync after 5 or 6 days and start spitting out orphans?

I have to restart it every few days just to make sure this does not happen. I am running latest linux mint and i've downloaded precompiled latest okcash 4.0.0.4 ubuntu x64 wallet.
I had same problem with 4.0.0.3 which i compiled myself.
