A few things come to mind (in no particular order): 1. 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 occurri= ng? 4. What do the following sysctls print out? kern.maxvnodes kern.minvnodes vfs.freevnodes vfs.wantfreevnodes vfs.numvnod= es 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, -Garrett
