53 blocks, each block is 128 KBytes = 6946816 Bytes.

JFFS2 needs around 5 free blocks in order for garbage collection to
work. Maybe your filesystem is full! Delete some files and run the
test again.

      Andrew
my jffs2 file size is 0x33a3d0 bytes. and I giben more than 5 free blocks in order for garbage collection.
Now Iam getting error like below

<5>jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0033a3d0: 0x727b
 instead
<5>jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0033a3d4: 0xb1a7
 instead
<5>jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0033a3d8: 0x0fdf
 instead
<5>jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0033a3dc: 0x3f91
 instead

now hanging. Pls provide the solution.

Thanks & Regards 
Srinivas Rao
