Ok
So I went and tried the same setup with a difference:
original setup:
1 controller on solaris 10 (sparc), with 2 linux mysqld backends.
now:
1 controller on linux with 2 linux mysqld backends

I tested and I didn't have the problem of the controller hanging..
and controller keeps getting connections while backing up/enabling a backend
+ enabling the backend doesnt take too long like with a solaris
controller...

it seems to hang right after a backup is finished and it try to re-enable
backed up backend

what could be the solaris problem ?
(I use same java 1.4.2 for the controller and 1.5.0 for myositis on both
OSs)

Thanks
