@alager, some followup questions:
a) How often does this occur?
b) Can you check if this mostly occurs when you are moving from montage view to System status view or does it happen when transitioning from other views to System status as well?
c) When this occurs, can you check via your network tools how many connections are active from ZMNinja to ZM?
thx

a) It's only happened once that I've noticed
b) will keep an eye on the behavior
c) I have wireshark, I'll see if I can catch it.

So the previous comment should have said I had 4 apache processes running.
Configured was 2, with 1 min spare and 5 max spare.
I've changed it to:
4, with 2 min spare and 4 max spare
now I'm not seeing the timeouts....I'll keep an eye on this.

Interesting. So Apache dropped that API HTTP request then? I see in your logs that it got a "daemonCheck" and then it got a "getLoad" but never received a "diskStatus" and my app returned an error, so does that mean the apache process just dropped that connection? Is that how Apache's limit works? I thought it would queue it up. The fact that you increased these limits and the problem is not recurring implies its not the app browser that is causing this issue, then.

running 6 apache processes, I see an odd behavior here.
10.5.20.87 - - [28/Sep/2015:16:02:01 -0700] "GET /zm/api/host/daemonCheck.json
10.5.20.87 - - [28/Sep/2015:16:02:02 -0700] "GET /zm/api/host/getLoad.json
Even though the time stamp is within 1 second of the above two rows, these two rows below don't show up in the access log until almost 40 seconds later, and that is the moment that the page changes from "loading..." to 588.6GB for disk usage.
10.5.20.87 - - [28/Sep/2015:16:02:02 -0700] "GET /zm/api/host/getDiskPercent.json

Now running 11 processes, the delay between those two sets is now about 3 seconds wall clock time, as is the update for the disk usage, but the logs still indicate about 1 second.
Also of note, I have to exit zmNinja each time to test this, as the swipe down to refresh does not appear to refresh when the number of processes was 6 or less.
Now that it I have 11 processes, swipe to refresh is working.

@alager a large delay for disk status is normal - mine takes 15s - zm executes a Unix dF that takes a long time spending on number of events files.

is this still a problem @alager ?

no, once I increased the number of apache processes, these issues went away.
