Are you positively sure you've set the "users per logging process" higher
than the default?  Verify as follows:

this part of the output...]


note that the "current" column reads 128 -- we don't use user logging on our
database, so we've never had reason to "muck with" this setting -- I suspect
you might not have made this change and you are indeed hitting "the default"
[at 128 users]  (or perhaps a system patch/update "reset" it to the default
-- this is a sysgen item after all...)

(and, of course, you'll have to make a tape and "update" from this tape to
have it take effect, unless this is one that takes effect at the next "start
norecovery")
