[horde] Sessionhandler question

[Kevin Konowalec]

What is the most reliable method for handling sessions in horde?   
Currently I have the session handler set to an external MySQL  
database communicating via tcp/ip.  In my logs I'm noticing a lot of  
errors like this:

[emergency] [horde] Could not connect to database for SQL  
SessionHandler. [on line 252 of "/myserverpath/Horde/SessionHandler/ 
mysql.php"]

They intersperse and are intermittent... but eventually I have to  
restart apache because it gives me "cannot connect to database"  
errors.  Should I switch to the default PHP session handler?  If I do  
that what is the impact on the system?
