Vicibox 7.0.3 from .iso | Vicidial 2.14-579a Build 161128-1746 | Asterisk 11.22.0-vici | CLuster setup: 1 web 1 DB 6 telephony | No Digium/Sangoma Hardware | No Extra Software After Installation

We have 95 agents currently and we are recording all calls and as we increase the size of our staff we are starting to have time sync issues with only 2 of the 6 nodes.

this is the 2 that are giving us problems



this is one that isn't


all of the nodes are configured the same but the 2 in question are slightly older. My question is what process can we delay until after hours to avoid this?

1) Neither of your images posted.

2) Time sync errors are often not really time sync errors. How is your time sync configured? Is one server the ntp master and the other servers all feed off that one?

3) It's common for overload (CPU overload, out of network ports overload, out of apache process overload ... lots of available overloads!) to cause a backlog that overloads the system ... and then packets don't get to/from the web server to the agent ... and then a dropped packet between the agent web browser and the agent web server causes a "time sync" error because one of the responsibilities of each of those packets is to update a timing field.

IE: Dropped packet = no time update = "time sync error!" and logged out agent.

4) So what, precisely, is overloading (and no, posting your stock crontab is not particularly useful)
