Jim, 

 We have 1000 wireless units on one AMP server, the server is dual
processor with 4 gigs of memory. We have no problems with frequent
crashing. The server is now running too slowly so we are adding a second
server and plan to divide the wireless units between them by subnets. I
have changed the polling to 15 min. after I get the new server I will go
back to 5 or 10 min polling on both servers.

Subject: [WIRELESS-LAN] AirWave inquiry

I've seen a lot of favorable comments and reviews here and elsewhere 
about AirWave (network management app).   We've been using it ourselves 
for a while and really value the info we get from it ..... when it's 
working properly.

It's gotten to the point where we have to reboot it several times a day;

the load average creeps up to 12 or higher, and it becomes unusable. 
Even after a fresh reboot, usage is only barely tolerable.  We can't 
depend upon it in a critical situation.  We investigated putting it on 
new hardware (we're upgrading a number of our net mgt server platforms 
to Sun X4200s running Linux), but were informed by the AirWave folks 
that they don't have 64-bit support.  Not only that, but in further 
discussions, we learned that most of the components for AirWave are 
written in Perl, which isn't exactly the most efficient programming 
platform.    Disillusionment sinks in .... it's like learning from the 
Easter Bunny that there is no Santa Claus!

So, my questions to those of you that do wax enthusiastically to this 
day about AirWave:

1)  How many WAPs are you currently managing with a single Airwave 
appliance?

2)  What is the (average) polling interval used?

3)  Do you have multiple Airwave servers, and if so, how many WAPs 
managed on each one?  How do you plan to scale--additional separate 
servers, or a beefier single server?

4)  What are your server specs?  (Vendor, OS, number of CPUs and their 
speed, amount of RAM, number of active NICs, etc.)

5)  How is performance on your server?  Do you notice performance 
degradation over time?  About how much memory is used under average 
load? How busy are the CPUs under average load?  How much network 
traffic is generated from polling?

Also, optionally:

6)  How do you manage security concerns?  (i.e. most Airwave processes 
running as root, installed in /root, root ssh remote logins enabled by 
default on default port, most components are written in Perl which can 
easily be modified if the machine is compromised, compilers are 
installed locally, etc.etc.etc.)

Inquiring minds want to know (and want to get the statistics we need to 
manage the network).

Thanks in advance!
