On my Grid Control management-server (Suse Linux, OMS version a very large number of <defunct> processes arose what eventually caused the OMS not to respond anymore.

oracle   16987 15961  0 Mar03 ?        00:00:00 <defunct>

Noticed that the following error was popping up in the emagent.trc of a 10.2.04 – Grid Control-agent  on a specific node, every 5 seconds. Annoying, unnecessary:

By | 2009-03-16T20:56:12+00:00 March 16th, 2009|Categories: Database|
