Why does jruby complain about valid java_opts
- by brad
I have set my java min/max heap size to be the same as outlined in the Sun Docs for precise heap sizing using the following:
-Xms768m -Xmx768m
This works fine when I start tomcat, but if I run jruby from the command line it complains saying:
Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified
I read in the jruby docs about some -J-X params but it seems silly that I would need to explicitly override my normal jvm settings.
The problem arises when I do a deploy. I try running jruby -S rake db:migrate on my server and it complains.
Is it true that I need to explicitly override my JVM settings when running jruby? It seems as though ANY Xms/Xmx values cause jruby to complain.
Update
So it seems that some settings do in fact work. For instance all of these work:
Xmx256m Xms256m
Xmx512m Xms256m
Xmx512m Xms500m
But these don't:
Xmx512m Xms512m
Xmx512m Xms501m
Xmx768m Xms512m
