...eing, so the vnlru process goes to sleep for 3 seconds without signaling anything. Then it wakes, tries again, same result. Current constraints are: - v_type is not VNON or VBAD - v_object is NULL or v_object->resident_page_count < trigger - VMIGHTFREE(vp) is true - can acquire vp->v_interlock I tried adding code which uses only the following constraints if no nodes could be freed the previous time: - VMIGHTFREE(vp) is true - can acquire v_interlock However, few nodes meet these constraints either. Which of the following approaches seem best: 1. Can I do away with some of the VMI...

Hi, my FreeBSD-9/stable machine (FreeBSD freebsd-tower.goebo.site 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #2 r241044M: Sat Sep 29 12:52:01 CEST 2012 lbo@freebsd-tower.goebo.site:/usr/obj/usr/src/sys/GENERIC i386) crashes reproducibly when rsync-ing files to an NFSv4 share on the FreeBSD machine. The crash makes the system reboot. The crash creates files in /var/crash which may be obtained
