hobbit color-changing issue

Hello,

I have a small hobbit issue. I want hobbit to go red every time the word "/evicted/" shows up in /var/log/messages on some hosts. So the part in /hobbit-clients.cfg/ is as follows:

    HOST=%cn4[3-6]*-hp
    PROC    "%syslogd" 1 1 red
    PROC    "%/usr/sbin/nscd" 1 red
    PROC    "%iscsid" 2 2 red
    LOAD    16.5 20.0
    LOG     %/var/log/messages %(?-i)evicted|Oops|ALERT|NOTICE COLOR=red
    LOG     %/var/log/messages %(?-i)LustreError|WARNING|FAILED|kernel|failing|ILLEGAL COLOR=yellow

The Part in client-local.cfg:

      [cn44-hp]
      log:/var/log/messages:10240
      ignore MARK
      trigger ALERT
      trigger .*(dumping log to)|(evicted).*
      file:/var/log/messages

The Issue: Every time I put the word "/evicted/" manually in the messages file, hobbit will go red for about 15 minutes. That's fine. If I put a second line with the word "/kernel/" in the messages file, a second (yellow) line appears in the mesgs column. That's also fine. Hobbit is still red, but stays that way only for about 15 minutes. After the 15 minutes, it changes to yellow and the "/evicted/" warning is gone. It stays yellow for another 15 minutes, and then it turns green.

The messages file is really small (under 10 KByte) and not much is being written in it. That's why hobbit must stay red all the time!?!

I searched for the number 900 in server/etc, but nothing matches (exept some proxy configuration). Does anyone have an Idea what or where the problem could be? Greetings Georgi
