salt: Salt-minion crashed when "Attempt to authenticate with the salt master failed"

Hi all,

My OS is CentOS 6.5. I find an issue that salt-minion often crashed when “Attempt to authenticate with the salt master failed”.

#On minion
/etc/init.d/salt-minion status
salt-minion dead but pid file exists

Can we see some debug logs on the master during the authentication failure? I’m thinking there may be more information there. It might also be useful to delete the minion’s key from the master and then re-accept the key, there may be some corruption or something there.
