The X100P cards are nasty.  The X101Ps aren't much better IMO.  In my 
experience I've never had good luck with multiple cards in one system.  I'd 
try a TDM02P (the normal and supported equivalent).  The fact that a totally 
new system didn't do anything to help either indicates that it's outside your 
system (is your network busy during office hours and not afterward?  Flood 
the network after hours with similar traffic and see if the results are the 
same) or even outside of the office (are these calls going through FXO or out 
to VOIP termination?)...  

I know the last thing you want to do right now is spend more money.  perhaps 
if you contact Digium you might be able to get a 15 or 30 day money back 
trial.  

That brings up the question -- have you contacted Digium for support?  They do 
support their cards very well.

I've not heard of problematic TDM after the latest rev (H) of the TDM card and 
the latest rev (unsure of the identifier) of the FXO modules.
