Hi, I had the same problem with ODS 7.14.UD6.on AIX 4.2.1. It has happened = twice this week. Everybody just hang and i could not even do a onmode -y properly. There= was a message saying no respond from the server. And when i did an oninit, the system= just hang on Logical Recovery and could not bring the server online. I had to reboot= the OS to get the server back online again. Any clues? ---------------------- Forwarded by Poh Hoai Kang/Malaysia/IBM on 10-31= -97 04:03 PM --------------------------- informix-list-owner @ rmy.emory.edu 10-30-97 01:16 AM Please respond to "germonpre_guy/dis@bekaert.com" @ internet To: informix-list @ rmy.emory.edu @ internet cc: Subject: Checkpoint blocked ? On AIX 4.2 with OWS 7.20.UC2, I had a deadlock situation twice in a short time : nobody could work, and an onstat gave the message : checkpoint required= , blocked. I had to stop Informix (onmode -k) and restart (oninit). I guess that some user threads where blocking the checkpoints ? Guy =
