Thoughts:

If you're truly out of private storage I'd expect an IEA message for a
failing GETMAIN or STORAGE OBTAIN. Does anything other than browsing the
SYSUDUMP support the theory of exhausted storage? That is, exhausted but
not (yet) to the point of a GETMAIN failing...

Changing the SYSUDUMP to SYSMDUMP (with a suitable dump-shaped allocation)
would nmake things easier to read and search. And you'd be able to see at
least some of the trace table. But really you want an earlier dump - LE and
whatever IDI... is (debugger?) are all gonna be in there ahead to mess
things up.

So if possible you probably want a SLIP, but if you're not actually getting
a GETMAIN failure then that'll be harder. You could do a SLIP on any abend
- yeah, it'll probably catch something you don't care about, but then maybe
it'll be the real problem.

I don't seem to have enough disk space for an SVC dump.

That's easily fixed, but an earlier transaction dump taken by LE is
probably beter than a later SVC dump.

No. Subpool 2 is not something I remember bumping into. I don't think it's
LE or any core MVS service - it's a user subpool (private and no privs
required) so I'd guess it's a "user" program running in your address space.
Again, that IDI...?

I forget where, but you can force the allocation for a transaction dump to
go somewhere else.

The above is probably useless. LE is notorious for clobbering the useful
info before it "summarizes" what's left for you.

I keep harping on this because I don't know what IDI... is. But it's a
likely culprit, in my view.

Again, SYSMDUMP.

Keep us posted.
