The Informix Tablespace services crashed with KeyError ('system_pagesize') when the monitored host still runs a mk_informix agent plugin from before Werk #17873. The check now falls back to the previous space calculation for such agent output. Since the blobspace size fix of Werk #17873 only takes effect once the updated mk_informix plugin is deployed, the service output points out the outdated plugin and asks to update it.
