Problem
Searching through Attachments causes numerous OutOfMemory errors.
Troubleshooting
-
If items with the OutOfMemory errors are exported and searched again, do they get the same errors?
-
Is the version of DA 32-bit?
Cause
This problem is generally caused when a 32-bit version of DA is run against a large dataset in one task. 32-bit processes are limited to 4 GB of memory, no matter how much RAM is on the machine. Especially with fast processors, having large sets of data run with one limited task can cause the OOM errors.
Solution
-
Break up data into multiple folders then use multiple tasks (i.e., split) to search them
-
Export OOM exceptions and research
-
Upgrade to 64-bit Office/DA
