Hi Kamil,

>>> Well. I have this again  after a week or something like that. But since

The error happens in check_version() in storage/ovdb/ovdb.c:

     ret = vdb->open(vdb, NULL, "version", NULL, DB_BTREE, _db_flags, 0666);
     if (ret != 0) {
         vdb->close(vdb, 0);
         warn("OVDB: open: version->open: %s", db_strerror(ret));
         return ret;
     }

I think _db_flags is DB_CREATE.
I do not know what can cause the pthread lock failture at that time.


https://community.oracle.com/thread/2619648 mentions an issue in 
virtualized environments.  Other discussions mention a limit in file 
descriptors.
Sorry for not being of useful help :(
