Bad outcome of batch preprocessing sequence

For some time now I have been unable to complete a batch preprocessing sequence even if I have the latest version and update plugins every time I start SNAP. My graph contains:

  1. Apply orbit file
  2. Thermal noise removal
  3. Calibration
  4. Multilook

I try to process 5 S1A_IW_GRDH_1SDV dual polarization scenes dating from between March and April 2018 and that cover Northern Guatemala.

Some of the scenes (the older ones and usually just 2 of them) are processed well, but the others just don´t have any meaningful data. The process creates a huge file (17 GB) in the log directory (file created = heapdump.hprof.old). I´m attaching the resultant log file.

Can someone help me correct this issue? Thanks.

I suggest you to have a look at this other discussion:

I encountered a similar problem with images acquired after March 2018.
