Subject: innodb error 995
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 operation. InnoDB: See http://www.innodb.com/ibman.php for installation help. InnoDB: See section 13.2 at http://www.innodb.com/ibman.php 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 error?
a few users have reported this Windows error. I believe it is a bug in Windows.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/debug/base/system_error_codes__500-999_.asp
"
ERROR_OPERATION_ABORTED
995 The I/O operation has been aborted because of either a thread exit or an application request.
"
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/base/readfileex.asp
"
The ReadFileEx function may fail if there are too many outstanding asynchronous I/O requests. In the event of such a failure, GetLastError can return ERROR_INVALID_USER_BUFFER or ERROR_NOT_ENOUGH_MEMORY.
To cancel all pending asynchronous I/O operations, use the CancelIo function. This function only cancels operations issued by the calling thread for the specified file handle. I/O operations that are canceled complete with the error ERROR_OPERATION_ABORTED.
"
But InnoDB does not call CancelIo.
Do you happen to have a Microsoft support contract? You could report this to Microsoft.
Any help would be useful.
Thank you
-Ben
