Kind-of sounds like I/O contention... what's your disk configuration? Do
you run RAID? If so, what kind? What do you observe if you monitor
"iostat -x 5" while the problem is occuring?
Art,
yes RAID-1
Do the relevant pqact(1) configuration-file entries use the "-flush" or
"-close" option?
Steve,
yes..except EXEC entries, are they needed there?
How are you dividing out the write tasks with LDM? Each pqact only has 32
pipes, so if you are attempting to fit too many products through those
available pipes, there will be lags.
Install system monitoring tools like 'dstat' and 'sysstat', monitor the
disk IO rates before you do something drastic like reformatting or
changing filesystems.

When I have seen problems before, it is almost always a LDM configuration
issue and not having enough pqacts running.
