Is there a max scratch disk size limit (set by some parameter) or is it simply the available unused space on the target scratch drive?

I'm running a large sol 111 for a random response analysis (nastran+patran).

Windows 10 os.

solve=auto

I'm getting the fatal msg 1250 (BIOWRT) and the msg "There is not enough space on the disk. The culprit appears to be the scratch file which is correctly directed to the intended scratch directory.

My scratch directory sits on an empty 1 TB HDD. After the long run fails and exits, many of the scratch files are deleted, some remain. Those remaining only take up a couple hundred GB and I can't see or find a history of available space that might have been very very small overnight.

So my question is this - Is the scratch space size limited only by the empty space by default OR is there possibly some parameter that says to limit the max scratch to some value, which may be much smaller than my 1 TB of empty space?

I think I've answered my own question now.

I dropped in a new 6TB empty drive and pointed the run scratch dir to that new drive and it's still running. So, my problem was indeed one of running out of disk space and not simply exceeding some allotted disk space which was my question.

I don't know if it's still the case, but there was a SCRATCH limit back in the days that you could overwrite with SSCR=xxxMB to give it a max size of xxx (in MB)
