Collector cant handle File deletions

[gruselglatz]

Hi,

we have a Logfile from an very complicated system, so we collect it via the collector:

It is filled live, and every hour it gets deleted and a new file will be created, it looks like this:

/mnt/log/work-grnti_201601080900
/mnt/log/work-grnti_201601081000
.
.
.

so i created this input for the collector:

inputs {
  local-syslog {
    type = "file"
    path-glob-root = "/mnt/log"
    path-glob-pattern = "work*"
    message-fields = {
      "application_name" = "test"
    }
    charset = "utf-8"
    content-splitter = "newline"
  }
}

And after "rotation" i get this error and the collector STOPS working and is only spamming my log!

At the moment i work around with a crontab which restarts my collector every hour.

Thx for help
