i’ve got a several other services all using the same database server all set up identically but for the sites running on them, but it’s the server with wordpress sites that leaves behind 100 sleeping connections. are you sure it’s not wordpress doing something here?
edit: for those other people having this problem, can you list what versions of apache, php, and mysql you are running? we’re running apache 2.0.63, php 4.3.10, and mysql 4.1.11 – if anyone knows of any relevant bugs related to those versions that could cause mysql threads to persist in a sleep state, please let us know!
