I\'m having a weird issue using Zend_Db\'s PDO adapter for managing my database connections. All of a sudden, I\'m constantly hitting the connection limit on my MySQL server
first i'll ask: do you have any new core-dumps? (check apache error log).
second: from my grim experience having too many connections to the database usually means that you have too many apache processes not dieing properly. Usually this is caused by some long-running process, memory locks, etc. try to strace
some of your apache processes and see if they hang somewere or do endless loops.
Unless you have a significant increase in traffic you should not suffer from too-many-connection problems
