LGWR: terminating instance due to error 27062

Hi, All!

I have: Oracle 8.0.5.1 + Unixware 7.1.1 (with latest patches) Compaq Proliant8500 (8 x Xeon / 4GbRAM / a lot of HDD's) Database: OLTP + DSS - total about 35Gb datafiles, up to 350 connects. There are RAW-devices: Redo-logs, Rollback & Temporary.

Third time i got crash:

!Thread 1 advanced to log sequence 67434
! Current log# 4 seq# 67434 mem# 0: /d_ora_sys/ORC/RAW/log04-1ORC.ora
! Current log# 4 seq# 67434 mem# 1: /d_ora_sys/ORC/RAW/log04-2ORC.ora
!LGWR: terminating instance due to error 27062
!Instance terminated by LGWR, pid = 19410
!
!ORA-27062: skgfospo: could not find pending async I/Os
!Cause: This is an internal error. There should have been some
!async I/Os in the system, but a blocking aiowait indicates
!that there are no more I/Os.
!Action: Look for trace file, and contact Oracle Support.

After that I can startup instance and everithing seems to be Ok. First time crash was on another server, but DB was the same (a few monthes ago). Second and third times this error appeared during last two weeks...
Yes, I'll call to support on Monday, but I guess these Oracle guys won't help me...

People, what should I do with configuration of async I/Os? Help, please.....
