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.

(ITS#8106) Retry pwrite operations in case of EINTR
by milinevskyy＠gmail.com 17 Apr '15

17 Apr '15

Full_Name: Dmytro Milinevskyy Version: OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (92.132.131.166) On linux systems it's common to have system calls interrupted and restarted. LMDB should retry pwrites to avoid "false" failures.
