Socket Hang

Created a small client/server app in Perl that sends commands and data
over a persistent socket basically copying files from one machine to
another. Works flawlessly until approx. 1550 files (each 200k) are
copied and then just hangs--mostly 1550, other times 1545, 1552, etc.
The client just hangs on a write (as seen via truss). File systems
aren't anywhere near full, nor is memory any where near exhausted. I
assume (perhaps erroneously/egotistically) that a basic coding/algorithm
problem would rear its ugly head in a more random fashion and have thus
not posted the code. I'm guessing/hoping some sort of resource issue or
Perl/Solaris 'feature'. Anybody else run into this kind of phenomenon?
Environment is Solaris 5.8 and 5.6, and Perl 5.005, 5.6, 5.8. Profuse
thanks in advance.
