[Freeswitch-users] Max handles 50 exceeded, blocking....

[Brian Foster]

If you're running that kind of call volume, you might consider taking Avi's
advice and go for a ramcache setup. I think your testing really the limits
of what you can handle with the DB being on a disk. Maybe not, it depends
on what all you are doing with the DB. I would look into that possibility
though, it may give you better results.
