the kernel willautomatically release the cached memory, if available. If java reports an error, perhaps you didn't start the Virtual Machine with the appropriate parameters?
If I recall correctly from my java-days, try launching the VM with the
command. Example:
to allocate 128Mb of memory from the start, and 2048Mb as maximum.
If you're still having problems with java memory leaks, there are toolkits out there to detect leaks in your application. I've never used any, so I suggest you use plain old google.
HI
I'm a rookie in C programming and I'm working in Monta Vista Linux. I have to write a program that displays free memory. I have memtester(allready written by someone else) and now I have to type how much amount of memory tester will test and I want that memtester finds out himself how much of... (11 Replies)
Linux Kernels 2.6.16 and up provide a way to instruct the kernel to drop the page cache, inode and dentry caches on command. This tip can help free Linux memory without a reboot.
Note: This is a non-destructive operation. Dirty objects are not freeable, hence; you must run sync beforehand.

I was running a program and it stopped and showed "Out of Memory!". at that time, the RAM used by this process is around 4G and the free memory size of the machine is around 30G.

Hi,
we are experiencing very odd behavior. After "mkfile 1g <somefile>" the available memory seen through vmstat memory free column decreases by the same ammount. It doesn't matter where the <somefile> is located, even when the file is on NAS, the available memory decreases. When the file is... (2 Replies)

how I can know how much total and free memory I have in my AIX 5.3 server, and this is shown in megabytes or gigabytes?
Thank you very much. (4 Replies)

GIT-CHECK-ATTR(1) Git Manual GIT-CHECK-ATTR(1)NAME
git-check-attr - Display gitattributes information
SYNOPSIS
git check-attr [-a | --all | attr...] [--] pathname...
git check-attr --stdin [-z] [-a | --all | attr...]
DESCRIPTION
For every pathname, this command will list if each attribute is unspecified, set, or unset as a gitattribute on that pathname.
OPTIONS -a, --all
List all attributes that are associated with the specified paths. If this option is used, then unspecified attributes will not be
included in the output.
--cached
Consider .gitattributes in the index only, ignoring the working tree.
--stdin
Read pathnames from the standard input, one per line, instead of from the command-line.
-z
The output format is modified to be machine-parseable. If --stdin is also given, input paths are separated with a NUL character instead
of a linefeed character.
--
Interpret all preceding arguments as attributes and all following arguments as path names.
If none of --stdin, --all, or -- is used, the first argument will be treated as an attribute and the rest of the arguments as pathnames.
OUTPUT
The output is of the form: <path> COLON SP <attribute> COLON SP <info> LF
unless -z is in effect, in which case NUL is used as delimiter: <path> NUL <attribute> NUL <info> NUL
<path> is the path of a file being queried, <attribute> is an attribute being queried and <info> can be either:
unspecified
when the attribute is not defined for the path.
unset
when the attribute is defined as false.
set
when the attribute is defined as true.
<value>
when a value has been assigned to the attribute.
Buffering happens as documented under the GIT_FLUSH option in git(1). The caller is responsible for avoiding deadlocks caused by
overfilling an input buffer or reading from an empty output buffer.
EXAMPLES
In the examples, the following .gitattributes file is used:
*.java diff=java -crlf myAttr
NoMyAttr.java !myAttr
README caveat=unspecified
o Listing a single attribute:
$ git check-attr diff org/example/MyClass.java
org/example/MyClass.java: diff: java
o Listing multiple attributes for a file:
$ git check-attr crlf diff myAttr -- org/example/MyClass.java
org/example/MyClass.java: crlf: unset
org/example/MyClass.java: diff: java
org/example/MyClass.java: myAttr: set
o Listing all attributes for a file:
$ git check-attr --all -- org/example/MyClass.java
org/example/MyClass.java: diff: java
org/example/MyClass.java: myAttr: set
o Listing an attribute for multiple files:
$ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java
org/example/MyClass.java: myAttr: set
org/example/NoMyAttr.java: myAttr: unspecified
o Not all values are equally unambiguous:
$ git check-attr caveat README
README: caveat: unspecified
