Hi Jim, > 1) Can I disable the watchdog - if so, how do I do this? Disable watchdog means ?? 1. If your question is disable monitoring of Amfnd by watchdog, then you Uncomment the following line from /etc/opensaf/amfwdog.conf: #export AMFWDOG_TIMEOUT_MS=0 2. If you don't want to start amfwdog, then you have to remove its configuration from Imm.xml.
> 2) Related to number 1 - who is "watching the watchdog"? If the watchdog > dies, how is this detected? What parameters are related to this? Amfnd is watching amfwdog by means of Health check. If watchdog dies, then Amfnd restarts it. Amf detects Amfwdog by down event when it dies. This is the same as any Amf component dies and Amf detects and restarts(as per configuration).
