IO_ERROR_BLOCK_SIZE

IO_ERROR_BLOCK_SIZE <size>

When the Windows kernel has allocated all of its paged-pool memory, it will not be able to perform many tasks and instead returns a STATUS_INSUFFICIENT_RESOURCES (0xC000009A) message. This is a restriction of 32-bit addressing (only 2GB addressable within the kernel), regardless of the amount of memory available in the system.

When the FairCom Server configuration option IO_ERROR_BLOCK_SIZE option is specified in the FairCom Server configuration file, a read or write operation that fails with Windows system error 1450 (ERROR_NO_SYSTEM_RESOURCES) is retried in blocks of the specified size. If any one of those read or write operations fails, the FairCom Server fails the read or write operation.
