We also have this problem, and it is clearly a Solaris 8 problem, as we
have two identical machines, one Solaris 2.6, one Solaris 8, both
running the same version of Qpopper, and both with the same load, as we
use DNS and round-robin to share the load. We run a simple Perl program
to simulate a POP session and time the response, and the response for
the Solaris 8 system under load is sometimes much worse, by an order of
magnitude, than the Solaris 2.6 system. We currently have an open call
with Sun about this, but they want us to apply the latest patches first,
which we hope to do next week. Do you use NFS ? We have a single mail spool
which is NFS mounted, and wonder if there is a concurrency problem with
NFS or file locking.
