Hi fellow monks,

I use DBI to connect to a MySQL database on a remote server (Linux). The main Perl application forks a couple of child processes which all do queries on the database. Each process opens its own database connection on startup.

The problem is that the main process (which forks three child processes at startup and when needed) suffers a lot of "DBI lost connection" errors. The child processes do the same, but never produce the same error: 

11-06-2003 13:31:13: [ERROR=5] DBD::mysql::st execute failed: Lost con
+nection to MySQL server during query at ... line 147.

Why is this happening only on the main Perl program and not in the child processes? They all use the same Database package. Can it have something to do with the fact this process forks of child processes and this causes the Database connection to be closed/lost?

Any input is highly appreciated.

TIA, Marcel
