Comment:

 Fixed in Q2A23

 The root cause is a failure to allocate enough memory to reconstruct the
 file from the JFFS2 piece list.

 Boot-loading files from JFFS2 didn't trigger this problem because that
 path, instead of using dynamically-allocated memory, reconstructs the file
 in-place at load-base, the large area reserved for boot image loading.
 The "more" command also uses load-base .

 The fix was to change the allocation strategy for the reconstruction area
 so that instead of allocating from the dma heap, the reconstruction is
 done in otherwise-unused parts of the very large region reserved for JFFS2
 data nodes.
