Hello guys,

I see lots of error messages when I command "tail -f /var/log/messages". This message filled the disk volume. Do you have any idea how can I solve this?

"reason"=\>"No mapping found for [@timestamp] in order to sort on", "index\_uuid"=\>"xMnKokzUSx-3rbWZzmiG3Q", "index"=\>".triggered\_watches"}}, {"shard"=\>0, "index"=\>".watcher-history-9-2019.05.16", "node"=\>"rm7GUkjkS1aP5XA18uk5Iw", "reason"=\>{"type"=\>"query\_shard\_exception", "index\_uuid"=\>"q7lNTyQ6QaavjCBRnIy70Q", "index"=\>".watcher-history ..."

Many Thanks,
