I'm seeing a problem with writing large files, when the file reaches 2 GB in size, the file becomes unreadable.
In the current isecoasmgr.log log file there will be an error like:
Jan 25 10:11:30 oldefortran ERROR AMOASScanner  Engine error occurred for the File Name: /scratch/local/fortran/xx
After executing these commands, I am able to write then read files >= 2 GB with no problem.
Should something be changed in the OAS profile?
It very well could be.
I've been working on trying to track down why some of my environment's SAS application servers are hanging / crashing during an On-Demand Scan. In the case of an On-Access scan I wouldn't rule it out. Depending on the amount of resources being used / the file that's being scanned I believe it could cause this problem.
I was unable to confirm with my Linux Support team if we had seen a kernel panic error on our systems, but that does sound like something we've encountered due to scanning. It seems that over utilization of system resources could cause this. Scanning a file that's a decent size can definitely cause problems.
