is this when the bitcoin cash crap started? was the 0.15.1 release the catalyst?
No, it was not.
I have a problem with Bitcoin cash Bitcash (BCC) corrupting the Bitcoin (BTC) database. I have to reindex both and still they get stuck at the fork of BCC off of BTC chain on August 1, 2017.
Anyone else been having this problem??? any solution? perhaps running BTC and BCC on different computers?

any other solution to the corrupting DB problem? - Thanks
Use a custom datadir for one of the nodes. Both will attempt to use the same datadir and that will be very problematic because they are two distinct blockchains.
