ASM Cookie assistance

Hi all.

 

 

Since upgrading to 11.2 we have suffered with 10's of thousands of Modified ASM Cookie alerts each week. I understand that the ASM cookie is session based so would expect these to clear over time since the upgrade but this doesn't appear to be the case.

 

 

Does anyone know of occurances where an old ASM cookie might hang about for some reason?

 

 

Thanks in advance for any info.
