Has anyone else out there lost messages sent thru PVM?

I'm setting up a simulation able to add and integrate new
tasks dynamically. As you might expect, there's a flurry of
messages sent each time a new task joins. Start up of the
entire simulation tends to magnify this effect. Everything
worked fine until I began increasing the number of tasks.
Now I notice that some tasks are sending the appropriate
messages, but the messages aren't being received at the
other end. This effect doesn't seem to be tied to any
specific task or computer. In fact, sometimes it seems
to work just fine. Also, PVM isn't flaging any errors.

PVM is reliable, right? So clobbered messages should
automatically be resent. Even so, I buffered the start
up with sleep commands to ease network traffic. No help.

Any ideas?

BTW I'm using mostly IRIX5 machines with PVM 3.3.11.
