Subject:innodb error 995
View as plain text  
Hi I'm running version MySQL 4.0.20a-debug
windows server 2003
on a dedicated database server with an external SCSI RAID array with a  
1 TB of disk space  (over 400 GIG free)

1 gig of RAM

basic settings
key buffer 512 MB
sort Buffer 32 Mb

innof db
Buffer Pool Size 512 MB

my innodb datafile is about 200 gig is size and I have 6 innodb  
databses. 3 are very large 40+ gigs with about 800 million records.
The other 3 are very small few MB is size. Every two weeks I rebuild  
one of the large db and use the other 2 as backups.
This configuration as worked fine for the last 2 months.

I was in the process of rebuilding one of the large databases when I  
got the following error.

050214 16:46:56  InnoDB: Operating system error number 995 in a file  
InnoDB: See for installation help.
InnoDB: See section 13.2 at
InnoDB: about operating system error numbers.
InnoDB: File name .\ibdata1
InnoDB: File operation call: 'Windows aio'.
InnoDB: Cannot continue operation.

after restarting mysql, innodb rolled back my tables in the db that  
crashed and the rest of my data seems fine.

I have googled around and there seems to be some info that this errors  
is some kind windows driver. Is there any more info regarding this  

Any help would be useful.

Thank you
