Therefore, the amfregister command waiting for IMFD gets stuck. * 3331998 (3341320) Syslog gets flooded with "Cannot delete event (rid %d) in reaper" error messages.

DETAILS OF INCIDENTS FIXED BY THE PATCH --------------------------------------- This patch fixes the following Symantec incidents: Patch ID: 6.0.300.300 * 3267240 (Tracking ID: 3259682) SYMPTOM: Imf registrations for disk group resources fail. DESCRIPTION: If vxconfigd is unresponsive, then IMFD becomes unresponsive and imf registrations fail for disk group resources. Subsequent attempts to unconfigure AMF will also fail. RESOLUTION: The IMFD code is modified to fix this hang. * 3331998 (Tracking ID: 3341320) SYMPTOM: Syslog gets flooded with "Cannot delete event (rid %d) in reaper" error messages. DESCRIPTION: This was a harmless error message which appeared in syslog. RESOLUTION: AMF code is modified so that the error message does not appear in the syslog. Patch ID: 6.0.300.200 * 3230303 (Tracking ID: 3248251) SYMPTOM: AMF driver panics the machine while monitoring online processes. DESCRIPTION: For certain Linux kernel versions, when AMF is monitoring an online process, AMF panics the machine while accessing kernel memory. The panic string looks something like "BUG: unable to handle kernel paging request". RESOLUTION: Symantec has fixed this issue by modifying the AMF code that accesses kernel memory. Patch ID: 6.0.300.100 * 3090243 (Tracking ID: 3090229) SYMPTOM: AMF driver panics the node when vxconfigd is unresponsive. DESCRIPTION: The libusnp_vxnotify.so library used for disk group notifications, goes into an infinite loop when vxconfigd daemon is unresponsive. This causes AMF to enter an inconsistent state as a result of which AMF driver panics the node. RESOLUTION: Symantec has modified the AMF driver and libusnp_vxnotify.so library, to address this issue. * 3097346 (Tracking ID: 3097342) SYMPTOM: AMF driver panics the node when AMF is being stopped. DESCRIPTION: When AMF driver is being stopped, it stops the IMFD daemon. The code to handle this sleeps while holding a lock. This causes AMF driver to panic the node. RESOLUTION: Symantec has modified the AMF driver to fix this issue.
