Hello misc@, A customer system of mine has problems with the system since this morning (happened 3 times so far). The dmesg shows a large number "scsi_xfer pool exhausted" messages.
Right now I have no idea on how to debug this any further. Cluestick more than welcome $ dmesg OpenBSD 6.1 (GENERIC.MP) #7: Mon Jun 12 20:41:01 CEST 2017 rob...@syspatch-61-amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 2026598400
