Quick thoughts:
1. RLSE
Check RLSE, or SMS RLSE (management class parameter).
It can be the reason in case when the dataset is closed and then reopen
again.
2. Change DD, create permanent dataset. make the allocation twice, see

you are talking about the largest formated record w/o key.

Charles,
my response has nothing to do with track capacity, but since you mentioned an
unexpected SB37-04 and previously talked about a blocksize mismatch between JCL
and actual allocation ...
Is the user's program, by any chance, a COBOL program?
Does the JCL hardcode a blocksize value

Thanks. The program (the subroutine in question, anyway) is in
assembler.
The DCB is coded without BLKSIZE
Wheeler posted the track capacity formulae for 3375 and
3380, which are trivial compared to the 3390. I tried to use the documented
formula once, but found it too convoluted to use. Use a program or a chart
for
3390.

Maybe I'm missing something here, but what does track capacity have to do with
this? This is a problem that can clearly happen well within the allocation
specifications by running out of extents, not having enough volumes available,
or even filling up the VTOC.
