Hi gentlemen,
I got the message below when I experimented with Access Security:

>CA client: A call to "assert (status == 0 || status == S_asLib_asNotActive)" failed in ../camessage.c at 1289
>Please send a copy of the output from "tt (0x1e1ad0)" and a copy of this message
>to the author or "[email protected]"
>This problem occurred in "@(#)Version R3.13.0.beta.11 $$Date: 1997/10/15 14:41:16 $$"
>task: 0X273d28 taskwd
>task 1e1ad0 CA client suspended

Output from "tt ..." is following:

>-> tt (0x1e1ad0)
> 5f3c8 _vxTaskEntry   +10 : _camsgtask (b, 0, 0, 0, 0, 0, 0, 0, 0, 0)
>2e40f2 _camsgtask     +342: _camessage (215fe8, 21a044)

>value = 0 = 0x0

This happened under such circumstances:
At first I booted IOC with Access Sequrity disabled.
Then on the IOC console I typed:

asSetFilename("<my Access Sequrity configuration file>")

and then:

asInit

At first it looked OK. When I tried to perform CA put (using "caput" command
from Unix) from host which didn't have write permission in AS config file 
I got error message that "caput failed". While from the host having write
permisssion this command executed successfully. And then I tried to open
an MEDM display dealing with channels in my IOC. I did it on the host with 
write permissions. And after this attempt I got this message and MEDM display
couldn't connect to channels.
  If this information helps, i'll be glad.
Best regards,
V.Korobov.
