getting system:save error permission denied and cannot open save session with host during legatto backup

During our nightly backups, the following is happening:daemon.log Line:6019 Pct:98% 06/11/03 00:05:48 nsrd: ddck220:/wsi01/emc11/data04/INDEXES_a.dbf done saving to pool 'First Drive' (ddck220.137) 287 MB 06/11/03 00:05:51 nsrd: ddck220:/wsi01/emc16/nsr/index/ddck220 saving to pool 'First Drive' (ddck220.137) 06/11/03 00:05:58 nsrindexd: session start error for ddck220: 13 06/11/03 00:05:58 nsrindexd: session start error for ddck220: 13 06/11/03 00:06:07 nsrindexd: session start error for ddck220: 13 06/11/03 00:06:13 nsrd: media info: suggest relabeling ddck220.008 on ddck220 for writing to pool 'First Drive' 06/11/03 00:06:14 nsrd: media waiting event: backup to pool 'First Drive' waiting for 1 writable backup tape(s) 06/11/03 00:06:14 nsrindexd: session start error for ddck220: 13 mk_named_strpipe: Invalid argument 06/11/03 00:06:17 nsrindexd: session start error for ddck220: 13 06/11/03 00:06:23 nsrindexd: session start error for ddck220: 13 06/11/03 00:06:27 nsrindexd: session start error for ddck220: 13 06/11/03 00:06:36 nsrd: ddck220:/wsi01/emc16/nsr/index/ddck220 done saving to pool 'First Drive' (ddck220.137) 3.4 MB 06/11/03 00:06:37 nsrd: ddck220:bootstrap saving to pool 'First Drive' (ddck220.137) 06/11/03 00:06:38 nsrmmdbd: media db is saving its data.

While this backup is taking place, I have a cron script submitting save commands. The problem is that during the time between the session start errors begin happening and when it begins writing to the tape again, some of the save command issued from my cron job are getting errors and the files are not being backed up. They are getting the error: system error,permission denied cannot open save session with "host". Would anyone have any idea what would cause this and how I could correct it. Any suggestions would be greatly appreciated as we have an outdated version of Legato and are not supported. Rgds, Ginny Merlino Data Device Corp
