[parsec-users] Dedup Memory Allocation

Following is the definition of MAXBUF (defined in file “dedupdef.h” )
#define MAXBUF (600*1024*1024) /* 128 MB for buffers */
In bracket it is written 128 MB but figure comes out to be 600MB. Is this a
bug or it means something else?
Because of this the malloc function in encoder.c fails. See the following
Enoder.c, Line 652
u_char * src = (u_char *)malloc(MAXBUF*2); à Succeeds
u_char * left = (u_char *)malloc(MAXBUF); à Memory allocation fails here
u_char * new = (u_char *) malloc(MAXBUF); à Fails here . Not enough memory
In 32 bit systems application gets max 2 GB memory. The above three
statements exceeds 2 GB limit.
