Changes to this message: intermittent I/O problems On August 9 there was a system crash which also causes the CXFS file systems to fail. Unfortunately the machine has not run stably since then. ----------------------------------------------------------------------- Update Aug 11, 16:15: The CXFS file spaces /ptmp1 and /ptmp2 have gone offline again; therefore further batch processing has been stopped. Update Aug 11, 17:05: The CXFS file spaces are online again. Update Aug 18: We have reports on intermittent failures of I/O in some jobs. The cause of this is being investigated; it may be related to the very high I/O load presently observed on the system.
