File descriptor 3 should be the file in the share you are currently processing. Also maybe do an strace as well to see if it's moving data or not? If it stuck in a select loop and never issuing reads/writes I claim it's deadlocked and needs to be killed. > Could this be related to the ~400 zombie processes this backup has > created? Unlikely. However I was hoping that the zombie issue would be fixed in BackupPC by now. > Also, if i were to stop this full backup, should i try again > with another full or an incremental ? ( i have no full backups in > backuppc ) A full. If you abort what you currently have transferred should be kept as a partial backup and the next full will reuse the files to get a complete full backup that you can use. I have had to run 4 or 5 full backups to get a base full backup that I could use on some of the larger partitions. -- -- rouilj John Rouillard System Administrator Renesys Corporation 603-244-9084 (cell) 603-643-9300 x 111 ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
