[thelist] Mysql errors

[CDitty]

Can someone explain what these 2 mysql errors are?  I found them in an .err 
file in my mysql directory.  I searched the Mysql website and looked 
through my book and couldn't find anything.  They are kinda self 
explanatory, but why are they appearing?

000725 17:34:12 Warning: setrlimit couldn't increase number of open files 
to more than 164
000725 17:34:12 Warning: Changed limits: max_connections: 30 table_cache: 62

Thanks
