malloc returning NULL if freemem high & swapmem low (MPRAS version 3.03 )
Hi All,
In my application malloc is returning NULL even though there is sufficient amount of free memory available but the swap memory is low.
Is this possible that, if free memory is high & swap memory is low, malloc will not be able to allocate memory & return NULL ?
Few details:
my system running on a x86 platform
2 Pentium III processors
MPRAS version 3.03
output of OS level and current kernel patch level 03.03.02.15
Commands I used to measure free memory and swap :
[ app001-0 root:/ ] sar -r 1 10
app001-0 app001-0 4.2 3.3 SDS2 06/03/08
06:56:32 freemem freeswp
06:56:33 513222 10197
06:56:34 513205 10197
06:56:35 513210 10197
06:56:36 513210 10197
06:56:37 513231 10197
06:56:38 513271 10197
06:56:39 513271 10197
06:56:40 513268 10197
06:56:41 513258 10197
06:56:42 513258 10197
Kindly look into the issue as I am not able to start my application in the above mentioned condition.
Thanks & Regards,
Ritesh

set_color - set_color - set the terminal color set_color - set the terminal color Synopsis set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR] Description Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple, cyan, white and normal. o -b, --background Set the background color o -c, --print-colors Prints a list of all valid color names o -h, --help Display help message and exit o -o, --bold Set bold or extra bright mode o -u, --underline Set underlined mode o -v, --version Display version and exit Calling set_color normal will set the terminal color to whatever is the default color of the terminal. Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey font color, while set_color --bold white will result in a white font color. Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator. set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of ncurses and recompile fish against it in order to fix this issue. Version 1.23.1 Sun Jan 8 2012 set_color(1)
