Description of problem:
My env has ~250 hosts, ~250 vms and several storage domains
*Every* click on the "New Server" / "New Desktop" buttons in my environment stucks webadmin's New Server/Desktop dialogs.

Please note that there is no output to the engine.log when clicking on these buttons.

Steps to reproduce:
Click on the Virtual Machines main tab in webadmin
Click on New Server or New Desktop buttons, the New Server/Desktop dialog is opened and immediately stuck with the running hour glass icon.

Version-Release number of selected component (if applicable):
rhevm 3.1, si25.2

Comment 1 Gilad Chaplik 2013-01-15 09:27:06 UTC
Currently I have 2 options (without debugging/logs - my machine can't handle rami's DB):

* we use search-backend to query hosts in this dialog, and it's limited to 100 (checked vdc_options), although there are ~250 (will send a patch for that).
* because the engine is loaded, the client stack a lot of queries to backend. actually using a Thread.sleep(2 sec) in search-vm, search-vds and reverting (http://gerrit.ovirt.org/#/c/9554/), I can easily reproduce the bug; 

but without the log or debugging I can't be sure in 100%. will try to reproduce it later on.

Comment 2 Michal Skrivanek 2013-02-25 13:45:42 UTC
so is that above patch in 3.2?

> so is that above patch in 3.2?

no, I sent a patch for it, but there are more work that needs to be done.
anyway I don't think bullet 1 is related to the patch, 2 is more likely.

Comment 5 Gilad Chaplik 2013-04-03 15:21:07 UTC
Currently unable to reproduce, please provide a reproducer based on latest 3.2 beta. Thanks.
