Hi Willy, I apologize if I wasn't clear. The comment in my previous email means that the servers were enabled, as expected. In other words, disabling servers seems to work fine ALL the times, while enabling servers works from time to time only.
In the scenario described by those logs (see my previous email), 2 servers are always enabled, while 3 are enabled/disabled at runtime. The following log 2012-03-15 08:14:18,112 Enabling reserves 2012-03-15 08:14:18,113 enable server www/i-95f89df1 ; enable server www/i-8bf89def ; enable server www/i-97f89df3 <--- line 2 2012-03-15 08:14:18,113 Expected 5 active serves, have 2, calling change_state() again <--- line 3 2012-03-15 08:14:18,113 enable server www/i-95f89df1 ; enable server www/i-8bf89def ; enable server www/i-97f89df3 <--- line 4 means that 3 servers were supposed to be enabled after line 2 (e.g., 5 servers in total), but were not (only the 2 'always on' servers are enabled). Hence, the command was issued again in line 4. This time the command succeeded. Here, instead: 2012-03-15 08:15:45,289 Enabling reserves 2012-03-15 08:15:45,290 enable server www/i-95f89df1 ; enable server www/i-8bf89def ; enable server www/i-97f89df3 <---- enabling works fine the command succeeded at the first attempt. I should mention that line 3 above uses a (different) socket which is open in interactive mode. There, the updated state is retrieved by means of 'show stat'. Does it make any sense now?
