What version of Apache and PHP are you running? Are you connecting to a Microsoft SQL server or a Sybase Server (I ask because of the reference to php_sybase_db, and since both would most likely make reference to that.) Is there a pattern to the crashing? (Heavy database activity?) If you are using FreeTDS to connect to a Microsoft SQL Server what version are you running?
