Hi,
   
       It seems that you inverted the times on the chart. 
   
  Regards,

Using 2-node clustered file system on DELL/EMC SAN/RHEL
2.6.9-34.0.2.ELsmp x86_64.

Config:

O2CB_HEARTBEAT_THRESHOLD=30

Kernel param: elavator=deadline (per FAQ)

These log items appear and the server crashes. Has happened twice now
at three week intervals, each time during a heavy IO operation:

Jan 15 16:08:29 db100 kernel: (3898,6):o2hb_setup_one_bio:371 ERROR:
Could not alloc slots BIO!
Jan 15 16:08:29 db100 kernel: (3898,6):o2hb_read_slots:507 ERROR: status = -12
Jan 15 16:08:29 db100 kernel: (3898,6):o2hb_do_disk_heartbeat:973
ERROR: status = -12

Jan 15 16:08:29 db100 kernel: (3898,6):o2hb_do_disk_heartbeat:973 ERROR: status

Can't find much on any of these errors…what is 507 ERROR status = -12?

Any help appreciated
