Acrobat Reader 9.1 on OpenSolaris Build 110

I installed the new Acrobat Reader 9.1 on my OpenSolaris Build 110 system.
Starting it as role root worked, but running as normal user didn't work.
I have a bash as standard shell.
The following profile is active for the user:
bash-3.2$ profiles
Brightness
Console User
Suspend To RAM
Suspend To Disk
CPU Power Management
Network Wifi Info
Primary Administrator
Zone Management
Basic Solaris User
All



When I start a pfsh and start acoread, the application works.


Here is a truss excerpt when starting with bash:


6663: lwp_create(0x0804712C, 0x0080, 0x08047128) = 3
6663/1: priocntlsys(1, 0x080471AC, 2, 0x080472CC, 0) Err#1 EPERM [proc_priocntl]
6663/1: lwp_detach(3) = 0
6663/1: lwp_continue(3) = 0
6663/3: lwp_create() (returning as new lwp ...) = 0
6663/3: context(3, 0xC83C0A60)
6663/3: schedctl() = 0xC8093010
6663/3: lwp_sigmask(3, 0xFFBFFEFF, 0x0000FFF7) = 0xFFBFFEFF [0x0000FFFF]
6663/3: lwp_exit()
6663: brk(0x0BEF1E38) = 0
6663: brk(0x0BF09E38) = 0
6663: brk(0x0BF09E38) = 0
6663: brk(0x0BF41E38) = 0
6663: fstat64(2, 0x080470A0) = 0
6663: write(2, 0xCCAAFE30, 48) = 48
6663: t e r m i n a t e c a l l e d a f t e r t h r o w i n g
6663: a n i n s t a n c e o f '

Seems as if the priocntlsys-call is the problem.

There is also a discussion on the adobe forum, but nothing other helps on
the Solaris platform.
