 When trying to apply a patch with opatch apply it fails with the following message:

[ Error during Patch conflict detection for apply patch Phase]. Detail: OPatch failed: ApplySession failed but Oracle Home has not been modified.Invalid argument

Using OPATCH_DEBUG=TRUE with the opatch apply command showed that it was failing with the following:

SystemCall::copyFile() failed, Invalid argument

Manual copies of the file involved worked successfully.

To determine if there was an issue with the patch file a checksum was perfomed with csum -h and it also failed with the following:

csum: shmat(): Invalid argument
