RE: [Webware-discuss] Webkit hangs after MySQL error (more info)

[Costas M. <co...@ho...>]

Understood, and agreed.  From digging deeper into this it does look like it 
was some sort of WK<->Mysql problem --probably MySQL barfed because of too 
many connections or something.  The problem is that MySQL recovered fine but 
WK did not.  Restarting WK is definitely the "nuclear" option, but I am out 
of ideas... my other one is wrapping DB cursor access with another class, 
catching the error and then either refreshing the connection and/or 
restarting WK --if that's possible, i.e. restarting WK from within itself...

Just brainstorming guys...
