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?

LMDB should retry pwrites to avoid "false" failures. In practice, writes to a file are "fast" and will always write at least one byte. But we've patched this as suggested, thanks. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
