+yaffs_tester.c lseeks and writes to a file in for loop then suddenly lseek( on line 238) returns the error EACCES.
+The handle to the file has not changed nor has the handle been closed.
+There is no reason for this error to happen and is therefor logged as a bug.
+
+if the emfile contains quite a few files then the same lseek will return a error code of 0 (see lseek_error_code_0_bug directory).

+
+yaffs_tester.c lseeks and writes to a file in for loop then suddenly lseek( on line 238) returns the error EACCES.
+The handle to the file has not changed nor has the handle been closed.
+There is no reason for this error to happen and is therefor logged as a bug.
+
+if the emfile contains quite a few files then the same lseek will return a error code of 0 (see lseek_error_code_0_bug directory).
+use the bug_emkfile to generate the error. The error only seems to happen now and again so the yaffs_tester may need to be run multiple times.
