Subject Cloudstack 4.3.0 UI impossible login problem : browsers hang
Date Fri, 17 Oct 2014 07:51:46 GMT


Configuration : Cloudstack 4.3.0. with two management servers (named 1 and 2) behind a LVS
with a configured charge of 100/1 for server1/server2 (direct routing)

Since two days, we have a login problem on server 1. The login pages load correctly. But after
typing the correct password (local or LDAP one) the browser hangs.
The first occurrence, two days ago. We restart the management server and the problem went
away. Today, we cannot anymore use the server 1 and we have to user the server 2.
Both servers are to our knowledge identical. And no change neither have been done on the infrastructure

Is anybody here has experienced a such problem or have any clue ?

The server ran for many weeks without any outage like this until now.

apilog.log when we have recurring events :
2014-10-17 09:05:44,446 INFO  [a.c.c.a.ApiServer] (http-6443-exec-442:ctx-8a23b456)
-- GET command=listCapabilities&response=json&sessionkey=null&_=1413529544423
401 unable to verify user credentials
But we have also the same INFO message on the working server.

Catalina.out :

2014-10-17 09:42:22,888 DEBUG [c.c.a.ApiServlet] (http-6443-exec-467:ctx-86fe168f) ===START=== -- POST
