We're seeing some intermittent connection problems with a persistent chat room, especially when connecting from Pidgin. The connection will work well for a person for a long period of time (days or weeks), then they'll be unable to access the room. No errors are evident on either the client or server side. Sometimes deleting the room from the Buddy List and re-adding it from the Room List is enough to solve the problem but sometimes the Zimbra server actually needs to be restarted.
1) Where should these errors be logged on the Zimbra side (if they are Zimbra errors)?
2) Is anyone else seeing anything like this behavior?
3) Is there a way to restart the IM service without restarting the entire Zimbra server?
Thanks in advance.
