We have a pretty big OLAP database, about 400-450gb. Its on its own VM with 24cpu and 74gb of RAM.I've had this problem intermittently in the past, but its become more frequent lately, to the point of it being a daily occurrence. The daily incremental process takes a couple hours each day (when it works). The error that is showing in the logs is:"Description: File system error: The following error occurred while writing to the file 'LazyWriter Stream': The I/O operation has been aborted because of either a thread exit or an application request. . "There will be several of these messages in the SQLAgent JobOutput against several different files within the OLAP database. Ive found some reference in searches to these thread exits being due to out of disk space issues, and Ive confirmed that not to be the case, we have over 200gb free on the drive at the point of the process failure as captured by perfmon..Is this just a matter of throwing a lot more memory at it, or is there something to be done within the SSAS instance's settings?Thanks for any input you all might have. Ive not found any hits with this particular message with regards to SSAS Processing failures.
