Console starts showing garbage after <enter> inside rcons.
What do you mean when said “restarting console”?
Console continue its work after:
- <enter> inside rcons/confetty
- bmc reset (console disconnected/console connected)
You’re absolutely right with ipmitool and conserver with the same servers we
were out of such troubles.

garbage to go away?
You said that ipmitool with a certain configuration did not trigger this?

Can you tell that it goes after exactly 24hours on the dot?
When console hung, does ‘ipmitool sol activate’ say ‘session already active’?
Yes,
# ipmitool -I lanplus -H 10.10.106.155 -U root -a sol activate

Does /var/log/confluent/consoles/<nodename> have any interesting events crop up?

Pyghmi will do keepalive as well, and if that’s the problem, it should be much
shorter than 24 hours. In fact, it should be checking if the SOL payload is
active and owned by confluent specifically every couple of minutes.
yes, thats correct

My last reply was incorrect. Problems still here. Im trying to find something
usefull inbetween confluent/pyghmi...
Confluent restart solves hangs/reopen all connections.
I think it isnt the best option to restart confluent 1 or 2 times in 24h.

It is Dell’s related problem, not 100% but…
Confluent from current master is doing things well :)
Thanks for pretty nice tool “confluentdbutil".

Looks like that problem was before… The fix was to use ipmitool with
keepalive(one from xcat repos).
Here pyghmi is used maybe that the reason?

Hi,
Im trying to completely migrate from conserver to confluent, but catch strange
behaviour.
Some of my consoles hangs ~after 24, so no any new messages in their logs or in
rcons.
I send messages with timestamp from OS >/dev/console every 30-60min and take a
look on them for monitoring purposes(consoles availability monitoring).
I can open rcons and hit enter, after few secs console is waking up(strange). I
didnt see it happen with conserver or maybe im wrong...
Some details:
- as i can see the bigest part of consoles with hangs behaviour are Dell idrac.
Doesnt matter which type of RacSerial or IPMISerial is in use.
- racreset hard/ipmitool bmc reset didnt do the things
- hit enter to console wake it up(for example with expect i can send \r\n\f,
but it looks bad)
- i didnt try to clean confluent's conf and restart it. Not sure it may help.
- HP consoles works well, same ipmi
- few consoles with custom pluging works good as well
So maybe my question is not about confluent, but if some of you have some
knowledge about same problems please share it! ;)
