Hi All,
My server has been running for 28 days now, and the q db f=d shows
that the counter for the buffer pool requests may have overflown (is that
a real word?). It may be a coincidence, but last night, I had about a
dozen client session fail to connect due to "out of space" error messages.
Here is the DB info:
adsm> q db f=d
Available Space (MB): 30,148
Assigned Capacity (MB): 30,148
Maximum Extension (MB): 0

The last number I remember seeing for buffer requests before it went
negative was around 2.1 billion.
And, here are some of last night's error messages:

I am going to reboot the machine shortly. Has anyone else seen these
types of error messages before? Does ADSM have memory leaks?
