Pausing 300 seconds due to database server lag
There is no problem. The bot is pausing for 300 seconds because of database
server lag.
Wikipedia (for instance) uses multiple database servers: one is the 'main'
server, the others are 'slaves'. The 'main' server is the one that
receives
writes (e.g. page edits), the 'slaves' get this information from the main
server.
When there are a lot of edits, there can be some lag between these, which
is called 'database server lag'. To prevent this lag from building up, the
site signals bots to slow down. This is what you are seeing.
