Seeing lita-slack crash frequently, as follows:

interesting. this might be OS related. you wouldn't happen to be running this on windows by any chance?

[jimmycuadra]

It might be this: litaio/lita-hipchat#3

No, running in Centos 6.6 within a Docker container. Let me know if any testing would be useful. Happy to help.

Okay, I have added this to the Dockerfile in my Centos environment:

RUN localedef -c -f UTF-8 -i en_US en_US.UTF-8
ENV LANG en_US.UTF-8  
ENV LANGUAGE en_US:en  
ENV LC_ALL en_US.UTF-8  

The container now reports this:

# locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=en_US.UTF-8

I will keep an eye on this to see if this issue recurs, and will report back.

Just reporting back that, after the above post, this seems to have stabilized.
