I have Actinic 4 through 8 lurking on my test system (and even different point versions via a few VMWare virtual PC's).

V5.1.6 passes the Advanced / Network Setup / Test on my local Windows XP Pro server with Apache 1.3.37 / Perl 5.8.7.

One area to look at if irregular Perl errors are cocurring is the number of items in the Cart. People have reported such errors when there are a large number of products in the cart (possibly combined with the products coming from Sections that contain a lot of products). The perl scripts consume so much memory or CPU time that server limits on Perl scripts can be exceeded.
