alerting on log messages

Hi all

I have this entry in client-local.cfg
---
[host=test_server_41]
log:/var/log/messages:1024000
ignore "%(Failed to fetch|Failed to parse|Failed to evaluate)"
trigger "%(ORA-04091|Failed to log off resource|Failed to log on resource)"
---

And in analysis.cfg I have:
---
HOST= test_server_41
    LOG /var/log/messages %(ORA-04091|Failed to log off resource|Failed to
log on resource) IGNORE=OCS color=red
---

Needless to say I'm getting alerts for more than just "ORA-04091", "Failed
to log off resource", and "Failed to log on resource".

Any ideas what I'm doing wrong?

Thanks
