in thread Using fork with DBI to create simultaneous db connections.

Either let each child have its own connection, or have a common process (eg the 'mother') handle all the database traffic, and use something else to communicate with this 'db-server-process', some sort of RPC or shared memory or... YMMV.

Okay, I'm having the same error and I'm getting the same with every other thread after the first thread finishes. Any thoughts? I'm doing just that myself; Global dbh in $this->{'dbh'} and each child defines it's own $this->{'_dbh-child'}. As soon as I call the first $this->{'_dbh-child'}->disconnect(), every other disconnect fails or spews out that error above, including the master {'dbh'}.

    The above can be omitted. Turns out the children where closing out the Global DBI object every time they where closing themselves out. It was causing the error. Moving the Global DBI call to a localized method fixed it right up.
