I have to do this under the pwrp user or under my local user?
Because pwrp user doesn't have needable permissions under which i may do such an action.

Ok!
I did this firstly under my admin user, then i restarted my comp and logged in as pwrp user,
value of shmmax was renwed, so after that i once again did an actions as i describe in previous post, so, after i have started ubuntu runtime monitor i saw the follwing:

F pwr bugcheck: <database lock was already created>, in file ../../rt_gdb.c, at line 660
%GHD-F-WEIRD, something is very weird in the database

So - another error.
Project not started.

After a failed start attempt you have to reset to remove shared memory and semaphores. Reset from the reset button in the runtime monitor.

I also did this action, but - i once again saw this:

F pwr bugcheck: <database lock was already created>, in file ../../rt_gdb.c, at line 660
%GHD-F-WEIRD, something is very weird in the database

May it bee something else?

It is the shared memory and semaphores, but if you for example tried to start proview as another user you don't have the permissions to remove them. You can see the owner with

> ls -l /tmp/pwr*

Remove these files (with sudo if needed).

You also have to remove the semaphores and shared memory in IPC and this will be done by a reboot. If you are not able to reboot you can see the shared resources with 'ipcs' and remove with 'ipcrm'.

Clearly I understand you that i must take an action to remove all semaphors and shared memeory like in your previous post?

In any case - i shall try and then answer what will happen.
