Recently, my Mysql server crashed leaving the following lines in error.log:
120124 11:36:51 InnoDB: Operating system error number 1450 in a file operation.
InnoDB: Some operating system error numbers are described at
InnoDB: http://dev.mysql.com/doc/refman/5.1/en/operating-system-error-codes.html
InnoDB: File name .\ib_logfile1
InnoDB: File operation call: 'Windows aio'.
InnoDB: Cannot continue operation.
In the link I've found "ERROR_NO_SYSTEM_RESOURCES", i.e., "Insufficient system resources exist to complete the requested service.", but I'm having no idea what resource could have been exhausted. I'm using Version 5.1.35 for Win64, at the time of the crash there were over 2 GB of free memory and multiple gigabytes free on each partition.
