Nearly once per day I'm getting a timeout that shows up in console like:
7:1:36 PM kernel: Areca RAID volume scsi command timeout (target=0 lun=0)
which corresponds exactly to when all postgres processes hang.
I'm reluctant to terminate pids because that tends to bring everything down. Is there anyway to resurrect these processes? I can't even open a new postgres window in terminal.
Also, is there any way to make postgres more tolerant of such timeouts? My System:
- Mac Pro (2013) with 12 core X 64GB
- OSX 10.10.4
- Postgres 9.4.4
the drives I'm using for tablespaces (4 of them) are:
- Areca 8050 T2
- each with 8 1TB OWC Mercury Electra 6G SSDs in a RAID 0 config.
