Eclipse updating indexes java heap space
The Java Hotspot Client VM uses the current heap size to calculate the free space.This means that the general tendency is for the Server VM to grow the heap rather than flush soft references, and therefore has a significant effect on when soft references are garbage collected.To work around this, some programs keep an "object pool", saving previously allocated objects in some freelist-like data structure and reusing them instead of allocating new ones. This may have worked before exact garbage collection became popular, but this is just not a good idea for any modern Java Virtual Machines. You can also try -agentlib:hprof=heap=all (or other option, try -agentlib:hprof=help for a list) Since 1.5, you can use jmap. The Java Hot Spot VM cannot expand its heap size if memory is completely allocated and no swap space is available.For more information, see jmap - Memory Map and Java Trouble-Shooting and Diagnostic Guide The VM prints "Out Of Memory Error" and exits. This can occur, for example, when several applications are running simultaneously.If you are still having problems please see the Java Trouble-Shooting and Diagnostic Guide I keep running out of file descriptors, what should I do?Certain applications will use a lot of file descriptors.
For 1.3, Max New Size is set to 32mb on Sparc, 2.5mb on Intel based machines.When this happens, the VM will exit after printing a message similar to the following.For more information, see the evaluation section of bug 4697804. The maximum theoretical heap limit for the 32-bit JVM is 4G.The only thing that you can do is to set the number of file descriptors allowed on the system higher.The hard limit default is 1024 and the soft limit default is 64.
