Hi all,

I was testing koha-dump on a new Ubuntu 18.04 server I put together, and I noticed that 2 out of 3 instances were failing to dump. Here are the errors:

mysqldump: Error: 'Access denied; you need (at least one of) the PROCESS privilege(s) for this operation' when trying to dump tablespaces

mysqldump: Got error: 1045: Access denied for user 'koha_<instance>'@'localhost' (using password: YES) when using LOCK TABLES

The first isn’t really relevant. The key one is the second one. You can workaround it by adding “--single-transaction” to mysqldump in koha-dump, but I’m still intrigued why it only happened to 2 out of 3 instances on that server.

I haven’t seen this issue on other 18.04 servers either. All the permissions and what not were the same across the instances, the database connections were sleeping, etc. Nothing made sense.

mysql> show grants for 'koha_<instance>'@'localhost';

| Grants for koha_<instance>@localhost                                       |

| GRANT USAGE ON *.* TO 'koha_<instance>'@'localhost'                        |

| GRANT ALL PRIVILEGES ON `koha_<instance>`.* TO 'koha_<instance>'@'localhost' |

Has anyone else had this problem?
