Unhandled exception - out of memory

I don't know if this is related to my computer only but anyway even if this is not brand new such things shouldn't happen.

My game hangs ocasionally with following error:

Code: Select all

Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: unable to create new native thread
        at java.lang.Thread.start0(Native Method)
        at java.lang.Thread.start(Unknown Source)
        at java.awt.EventQueue.initDispatchThread(Unknown Source)
        at java.awt.EventDispatchThread.run(Unknown Source)
I cannot replicate it at ease but it happens some and then. Usually when I switch to large view (but also during other actions). It got better when I started to switch Firefox off but still happens occasionally. Is there a possibility to add some try/catch so games does not hang after you spent 45 minutes on units movement?

Recently this 'event' was preceded by this one (still could play though):

Code: Select all

This happens to me too occasionally. The thing I do, which is the only thing I know to do, is to shut the game down (kill it with task manager) and restart. If this continues to happen too frequently for a particular game turn (or in general) I will also shut down other applications (e.g., browser, email).

I do the same but it happens quite often - is it possible to trace the place where it happens?

Realistically, that would require some sort of memory monitoring program (not free) and a significant bit of effort. Both beyond the means of a fan based dev team I'm afraid.

The game never crashes on me, but I have 12 GB of RAM in my computer. So I can't recreate this error.
