These cards have always been problematic for me.  

Make sure the cards aren't sharing interrupts. 
Always make sure you use filtered power (UPS or a good powerbar).  
You might get lucky and find that re-seating the card or changing PCI
slots helps. Failing that, try using a completely different PC.  

We've found a system from Shuttle (all intel components) that tends to
keep the card very stable - so we standardize on it when building
Asterisk boxes.

You'll probably find that stopping * and re-loading the card module
(wcfxs) will correct the issue (temporarily).  Aside from that, make
sure your customers know how to hit ctrl-alt-del on the pbx...
