[JFFS2] Running fsstress causes panic

[rohit h]

Hello all,
 I am running a filesystem testing utility 'fsstress' on JFFS2 running
over a 80MB OneNAND partition.
 The fsstress command line used is 'fsstress -p 3 -n 1000000 -d /tmp -l 0 &'
 This creates 3 processes with each process executing 1000000 operations.
 The testing board has 64MB of RAM.
 After around 5 hours, I get panic message pasted below.
 I have done the same test with the command line 'fsstress -p3 -n
10000 -d /tmp -l 0 &'
 This test goes through for 5 days without failing, after which I
ended the test.
 Can somebody throw some light as to why this is happening.
Thanks a lot
 Rohit
