Java’s default heap size (at least last time I researched it) is 128 MB. The latest version of Eclipse (i.e. Helios) is set to run with a default heap size of 512 MB. (see the eclipse.ini file in your Eclipse base path). Therefore, you are probably seeing this behavior because your application needs a heap … Read more
I have written a code and I run it a lot but suddenly I got an OutOfMemoryError:
We are getting “java.lang.OutOfMemoryError : unable to create new native Thread” on 8GB RAM VM after 32k threads (ps -eLF| grep -c java) However, “top” and “free -m” shows 50% free memory available. JDk is 64 bit and tried with both HotSpot and JRockit.Server has Linux 2.6.18 We also tried OS stack size (ulimit -s) tweaking and max process(ulimit … Read more
I have written a code and I run it a lot but suddenly I got an OutOfMemoryError:
This problem usually occurs when some process such as loading huge data to memory stream and your system memory is not capable of storing so much of data. Try clearing temp folder by giving the command start -> run -> %temp%
If I remember correctly, there is a strict standard limit for the memory usage in V8 of around 1.7 GB, if you do not increase it manually. In one of our products we followed this solution in our deploy script: There would also be a new space command but as I read here: a-tour-of-v8-garbage-collection the new space … Read more
This message means that for some reason the garbage collector is taking an excessive amount of time (by default 98% of all CPU time of the process) and recovers very little memory in each run (by default 2% of the heap). This effectively means that your program stops doing any progress and is busy running … Read more
Ultimately you always have a finite max of heap to use no matter what platform you are running on. In Windows 32 bit this is around 2GB (not specifically heap but total amount of memory per process). It just happens that Java chooses to make the default smaller (presumably so that the programmer can’t create … Read more

Parameters and local variables are allocated on the stack (with reference types, the object lives on the heap and a variable in the stack references that object on the heap). The stack typically lives at the upper end of your address space and as it is used up it heads towards the bottom of the address space (i.e. towards zero). Your process also … Read more
