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
