Fall of IDS 10

Hi! I have Informix 10.0 on Solaris 10. Today at midnight realize a level 0 backup with OnTape and onbar. Failure and the server generates these messages online.log Mon Mar 16 00:00:31 2009 00:00:31 Checkpoint Completed: duration was 0 seconds. 00:00:31 Checkpoint loguniq 330, logpos 0xa9018, timestamp: 0x18c31eb 00:00:31 Maximum server connections 2 00:00:31 Level 0 Archive started on rootdbs, dbspaceblob, dbspacelogs, s9_sbspc , dbspace_calendar, dbspace_calendar_index, dbspacecalendartest, dbspacecalendar uni, dbspacecontratostest, dbspacecontratosuni, dbspacelogisticademo, dbspacelog isticatest, dbspacelogisticauni, dbspacein002 00:00:37 Archive on rootdbs, dbspaceblob, dbspacelogs, s9_sbspc, dbspace_calend ar, dbspace_calendar_index, dbspacecalendartest, dbspacecalendaruni, dbspacecont ratostest, dbspacecontratosuni, dbspacelogisticademo, dbspacelogisticatest, dbsp acelogisticauni, dbspacein002 Completed. 00:00:38 Logical Log 330 - Backup Started 00:00:38 Logical Log 330 - Backup Completed 00:00:38 Fatal error in ADM VP at mtex.c:431 00:00:38 No Exception Handler 00:00:39 PANIC: Attempting to bring system down 00:00:39 semctl: errno = 22 The last message was written in online.log until it filled the file system after 8 hours 45 minutes.

It is the first time and I hope it will be the last. Even before I made backup at the same time and with OnTape and onbar. Search google and found few references to this problem and no version of 10.0, in these references do not give solution to it. Is this due to a bug? Thanks!
