this also happens with mysql storage, this looks like a resource exhaustion issue, we have too many connection to database in the same time so the kernal can't create new...

I think the error may comes from here: https://github.com/seaweedfs/seaweedfs/blob/dcc200fec058e51bbb3e4fe49744637fd16d01b2/weed/filer/abstract_sql/abstract_sql_store.go#L294-L342 we should close

I managed to workaround this by set this in filer.toml: ```toml connection_max_idle = 10 connection_max_open = 10 connection_max_lifetime_seconds = 3600 ```

I think https://github.com/appleboy/docker-backup-database/pull/21 would fix this

I have a working fork https://github.com/trim21/docker-backup-database/tree/master if you need it now, I'm trying to submit these changes to here.
