I have recieved a similiar error to the poster.

ERROR: buffer overflow in receive_file_entry
rsync error: error allocating core memory buffers (code 22) at util.c(126)

I also found a similiar error using here..

I have tested 2.6.6 and 2.6.8

This fix is for 2.6.8
The changes I have made to fix my error were in 

flist.c (489.c)

static struct file_struct *receive_file_entry(struct file_list *flist, unsigned
short flags, int f)

I changed the following lines:

        static char lastname[MAXPATHLEN], *lastdir;
        char thisname[MAXPATHLEN];

        if (l2 >= MAXPATHLEN - l1) {


        static char lastname[BIGPATHBUFLEN], *lastdir;
        char thisname[BIGPATHBUFLEN];

        if (l2 >= BIGPATHBUFLEN - l1) {

I haven't done full debugged this, but it compiles and runs, and does what I
want so far.

The cause for this, was very long file names.
