promotion failure

[Ken--@newsgroupstats.hk]

Just for your information.

My java app is running very well now. Thanks to all of you.

Today I got a promotion failure at uptime = 10 days and triggered a 4
seconds full gc.

It is not a big problem as I can restart my app weekly or manually trigger
full gc (by jmap -histo -live at night).
