My forum was down and after downloading the error log I found this error repeated tons of times:
[28-Jan-2017 18:50:06 UTC] PHP Warning: array_merge(): Argument #1 is not an array in /home/[server]/public_html/[forum]/dbtech/vbshop_pro/cron/autobump.php on line 60
The forum eventually came back up on its own, but I noticed that this error was also logged on previous days.
I'm not sure if this is a bug or what, but I've now disabled the "(Pro) DragonByte Tech: vBShop - Automatic Thread Bump" scheduled task because we don't use this feature anyway.
