I am constantly monitoring the cache-hit-% on our server, and from time to
time increase the buffer-pool.
I usually reset the bufpool-statistcs every second day.
My genral impression is that the cache-hit-% drops over time, when the
server has been up for a long time. So, the first question is, are there
still memory-leaks in the server that could cause this?

Today I took a look at the db-status. The server har been up for about 14
days. The buf-pool-statistics have not been reset during this period.

The total buffer-requests has obviously rounded 2 G-requests....

Is this a bug in the admin client or in the server?

The current server is
ADSM Server for AIX-RS/6000 - Version 2, Release 1, Level 5.13/5.13
running on AIX 4.2.0

The admin-client is (AIX)
Command Line Administrative Interface - Version 2, Release 1, Level 0.6G
