--047d7bd910b0d34afe0513f14c84 Content-Type: text/plain; charset=UTF-8 Hello, we've encountered this problem mainly on Android device. The kernel sends a fake signal and the baking storage(flash) is not so fast. I've noticed a typo in my patch for the macro DO_PWRITE in mdb_env_init_meta. The test should be done for EINTR, not EINVAL. Do you want me to resend the patch?
