We find out an possible reason for one hang up.
The time ISP did update and restart Apache was synchron to the time of the error logs.
Perhaps GlassFish does not like that.
But the main problem still exist.
Currently every day between 5:30 to 6:30 CET GlassFish hang up with this exceptions.
ISP increase max prozesses to 22000 and mysql connections, but nothing did help.
Seams they also have no idea, what they can do more:(
Dont understand, that it is so difficult for the admins to just determine which service (java,mysql,glassfish,...) opens so much files.
