We have been running a large Asterisk (4000+ peers) cluster for 9+ years, our previous cluster was running 1.4 and for the most part pretty stable. We have deployed a new set of servers on the weekend running 11.23.0. During all my testing the reload command was flawless when ever we need to reload changes we made. Now when I issue a reload command the server hangs for up to 20 seconds, during this time all callers are getting is dead air if they try to make/receive a call.
Does anyone have any idea this is a large critical system and requiring reloads is during the day is important.
