This is a long standing bug and is not easy to fix. It is fixed in the not yet release 3.5 branch. All connect system call are done in different thread. All bind system call are done in separate processes. planner, dumper, amcheck, amservice do not require to be setuid root. Only the new ambind program need to be setuid root.

Hello Folks, I think that this is an old bug that has come back in version 3.4.5. If one of the clients is not reachable for an ‘amcheck’, then I get multiple errors: ############# [root@beagle amandad]# su amandabackup -c '/usr/sbin/amcheck Journalier-VTAPE' Amanda Tape Server Host Check ----------------------------- NOTE: Holding disk '/amanda/stage/Journalier-VTAPE': 6194409472 KB disk space available, using 1048576000 KB as requested Searching for label 'vtape-4':found in slot 4: volume 'vtape-4' Will write to volume 'vtape-4' in slot 4.
