onbar coring when backing-up the logical logs of a whole backup

I have a customer running Solaris 8, NetBackup 4.5 MP1 and IDS 9.40.UC3. When running a whole backup, they can backup their physical dbspace data without errors/warnings, but when the backup starts into the logical logs we immediately see onbar core: 2004-05-05 15:27:37 24060 24058 Begin backup logical log 13895. 2004-05-05 15:27:37 24060 24058 Successfully connected to Storage Manager. 2004-05-05 15:28:12 24060 24058 ASSERT: file bar_xbsa.ecbarSendData() line 1331 - contact product support 2004-05-05 15:28:13 24060 24058 See also: /tmp/core.24060 2004-05-05 15:28:24 24060 24058 /ids_9.4/bin/onbar_d complete, returning 159 (0x9f) According to page 11-14 of the Informix Backup and Restore Guide, March 2003 Part No. CT1SLNA (the manual for version 9.40) and Informix twister article 1053470, onbar return code 159 is: "0x9f (159) BAR_BUG. A specific check for an unacceptable error condition during the execution of ON-Bar failed. This should be reported to Technical Support along with the complete contents of the BAR_ACT_LOG." Subsequent manual logical log backups are successful: 2004-05-05 15:40:40 25756 25754 /ids_9.4/bin/onbar_d -b -l 2004-05-05 15:40:40 25756 25754 Warning: BSA version is 1.1.0.This version does not match with the version(s) specified in /ids_9.4/etc/sm_versions. 2004-05-05 15:40:40 25756 25754 Warning: Assuming Generic Storage Manager. 2004-05-05 15:40:40 25756 25754 Begin backup logical log 13895. 2004-05-05 15:40:40 25756 25754 Successfully connected to Storage Manager. 2004-05-05 15:44:30 25756 25754 Completed backup logical log 13895 (Storage Manager copy ID: 1 1083769975). As I understand Informix support is blaming Veritas, though they haven't seen the core file. Has anyone seen a similar error, or can provide any insight? Any and all responses, including flames, are welcome. Thanks in advance. Brice Avila Minneapolis, Minnesota
