What does svn say before it dies? 2. What does df for the affected partition output? 3. Do you have syslog output that indicates where the starvation is occurring? 4. What do the following sysctls print out? kern.maxvnodes kern.minvnodes vfs.freevnodes vfs.wantfreevnodes vfs.numvnodes 5. What does top / vmstat -z say for memory right before svn goes south? 6. Are you running the import as an unprivileged user, or root? 7. Has the login.conf been changed on the box? Thanks, -GarrettReceived on Wed Dec 14 2011 - 19:04:19 UTC
