Something is wrong

[giusepperibbiano]

Hello all,
first things first. This forum has saved my life more than Fleming saved umanity
i run Vicidial for my call center and for partners.
The thing is this, i always used to work with vicibox 4.0.0(or 4.0.3, always preload iso-s) with updated svn for every instalation. asterisk 1.4,suse 12. old stuff, but goooood stuff.
never had problems. well sometime hdd breaks but i gues is nobodys fault.

than a took this wonderfull server. 2xquads (16threads) , 16ram. raid1 (2x125gb) SSD. i thought: "is time to move forward, so lets install vicibox 6.0.4. i was very happy about that. it has to keep alive something like 25 agents whith 6-9 adapt-tapered-ratio.
Here comes the nightmare. over 20 agents the server started to go crazy. at some point i was having only errors and warnings.
1) Unable to write to alert pipe on IAX2/127.0.0.1:41569-9628 (qlen = 77): Resource temporarily - a lot of them
2) exceptionally long voice queue length queuing to iax2 - a lot
3) timeout reached on 60 sec.

when i looked on sip show channels it gave me more calls than channels. i was forced to work a week like that, and at the first sunday BOOOOOM. installed back the old mighty vicibox 4.0.0 and everything is fine. now i have logged in 35 agents and averything works like a charm.
is the same machine, same ratio, same everything...
so my question is simple:
Why? Why in the same conditions vicibox 4 works much better than vicibox 6?

last thing, same isuee in other places. same problems in 3 other colleagues call centers.

Since we can't troubleshoot any of the problems (you rebuilt the system), there's no way to find out what you did wrong to cause all that (LOL). Vicibox 5 was better than 4. 6 was better than 5. 7 is better than 6.

Summary: You did not troubleshoot the problems one at a time when they were occurring. Now the system can not be fixed because it's gone. Given the odds, you had a slight misconfiguration issue (or three?) or perhaps a networking problem ... or any one of several hundred other things. Did you import or restore any settings? If so, note that settings from Vicibox 4 are not upgrade compatible with Vicibox 6. So bring the "data" along for the ride, but the configuration settings should be from the new system, along with modification of the admin->servers settings to be sure they match the physical server: especially the asterisk version (which is not the same from one Vicibox to the next in many cases)!

But if it's working ... who cares, right? LOL

Next time:
1) Never subject a post "something is wrong" or I'll send a baby over to your office to cry all day, as you deserve it.
2) Approach each problem one at a time and solve each one. If you get lucky, one symptom may lead you to a fix for others.
3) Don't wait until after you've rebuilt the server to ask what was wrong with the old one. Have you ever gone to a mechanic and asked him to diagnose the problem on the car you sold last month?
4) Try Vicibox 7.0.3. You may like it.
