i uses ps aux | less but it shows. Zero in all process.
Could you post it anyway? Also try scrolling to the right to see if there's anything off the screen.
This is the usual "oh my god linux uses free memory for cache" freakout. Cached memory counts as free memory. All that messing you're doing with vm modes is only hurting the system, it may actually be causing the problem, you should undo it. The problem isn't related to low memory.

Hi,
First of all I appreciate this group very much for its informative discussions and posts.
Here is my question.
I have one process whose virtual memory size increases linearly from 6MB to 12MB in 20 minutes. Does that mean my process has memory leaks?
In what cases does the... (4 Replies)

Hi.
This might be a strange request, but does anyone have any idea on a simple shell script that would use more and more memory as it ran? Like a purposeful leak.
I want to test the behaviour of an already running program when the machine runs out of memory.
Thanks! (4 Replies)
Hi All,
my client server application can work in two modes:
1) one direction - only client sends msgs to server
2) two directions - server gives 'answers' to client.
when program run in the first mode it looks OK, but when server answers to client than client's application exit its... (2 Replies)
Hi,
I am trying a database server which keeps a B+ plus tree structure and works on it.
I am trying to find the memory used/leak while executing this process.
I check the memory leak by using ps uax command.
When i execute a delete query i am sure that my code frees up the existing... (9 Replies)
I have written this code in C which reads a very large collection of text files and does some processing. The problem with this code is that there are memory leaks which I am not able to figure out as to where the problem is. When I run this code, and see the memory usage using top command, then I...

sync2
sync2(2) System Calls Manual sync2(2)NAME
sync2 - Flush file system metadata and data from memory buffers to disk
SYNOPSIS
#include <sys/mount.h>
int sync2 (
unsigned int POLICY ,
char *path);
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
sync2(): XSH5.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Flush the file system memory buffers to disk. The argument is one of the following: Flush all memory buffers. Specifying this flag causes
the function to behave the same as the sync function. See sync(2). Flush all memory buffers except those under smooth sync control. The
name of a file system or fileset. Specify the optional path parameter when you want to have the POLICY act only on that file system
instead of all file systems. Specify a NULL argument when you want to have the POLICY act on all file systems.
DESCRIPTION
The sync2 function causes file system data to be flushed (written) to disk. Which memory buffers are flushed to disk depends on the POLICY
argument.
If the policy is SYNC_SYNCPOLICY, all memory buffers are flushed to disk. If the policy is SYNC_SMOOTHSYNCPOLICY, all memory buffers
except those under smooth sync control are flushed to disk.
To which file systems the POLICY argument applies depends on the path argument. To apply the policy to one file system, name it in the
path argument. To apply the policy to all file systems, specify the path argument as NULL.
The writing, although scheduled, is not necessarily complete upon return from the sync2 function.
