Hello!
On one of my servers when i start natural i have a delay from 3 seconds until the login screen is displayed, on my other servers this is not. So i searchef for that and with “strace” i found out that when starting natural i get hundreds of read errors for the file “/tmp/.adabas_db201.watch”, this file does not exist on all of my other servers, does someone know what’s the sense of this file and why is it created on this specific server?
Adabas 6.4.0.00
Redhat 6.4
Naturl 8.3.3
I don’t recognize this as a “standard” file of either ADA or NAT, so I guess this is something site specific,
check if there is a Natural startup program running, referencing that file, in the environment experiencing
the delay.
Hello Wolfgang! Refering to your name i guess we should be able to speak german 
No, it is definiteley created when i start a adabas database with “adastart”, wen i stop the database with “adastop” the file will be deleted. This time i recognized that on my 2nd adabas 6.4.0.00 server the files also exist, it may has to do with the 6.4 release, do you have a 6.4 running?
Since the file is a hidden file many people may do not recognize ist.
Jetzt ab ich’s auch gerade bei deiner Orteinstellung gesehen das wir ev. auch auf deutsch schreiben könnten :))
Some new experiences, when i run “strace -t -o /tmp/natural.strace natural” i get:

Hallo Max,
we could, of course, discuss this issue in German, but that wouldn’t be fair to all non-german-speakers on the forum 
I didn’t have a 6.4 installed, but did so, especially for you, now.
And I still don’t see these files being created, so I still believe this is something site specific,
especially as you see it being read from Natural.
Please post your DB201.INI maybe we’ll find a clue there.
Cheers - Wolfgang
Hi, this is my configuration file of Database db205, the file “/tmp/.adabas_db205_watch” is also created for the database.

Perhaps there’s a mismatch between the Adabas Client and Adabas Server components on the problem server (he says grasping at straws ).
