Can anyone give me a pointer to what precisely I might do to correct the situation. The first three suggestions do not apply: # Reduce memory load on the system # Increase physical memory or swap space # Check if swap backing store is full

The situation requires a cold boot to correct and that ABSOLUTELY nothing be done in the user account except launching an X server prior to launching the application.

An earlier version of the application at least privides a logfile when it crashes

LogFile - too long to be reasonably opened by emacs, but "cat /hs_err_pid23337.log |less" works fine but, at least to me, is not helpful.

If you'll forgive me fumbling about in an area I barely know anything about ... I'll point out that Java sometimes means very different things by "out of memory" than we think it does, and in this case we're only finding out about it after it's filtered through the application logging. I think this probably means "Java has run out of the memory you said it could have." You didn't know you told it about how much memory it could have, did you? That's because there are default values, and it's a pretty common problem to bump up against them. (Again, not totally sure that's what's happening here.) I would try: export JAVA_TOOL_OPTIONS="-Xmx1024M" (You should perhaps check if this is already set FIRST, but doing this at the command line is specific to the current shell.) Then try running the application again. And read this: https://stackoverflow.com/questions/5374455/what-does-java-option-xmx-stand-... for a passable explanation of a horrible subject. Read not just the accepted answer, but the other stuff as well. I hope this is what you need. -- Giles https://www.gilesorr.com/ gilesorr@gmail.com
