Too many open files with flexcache

Hi,

I recently migrated my user's UAT NFS share from one SVM (9.9.1P12) with a regular flexvol volume to a new SVM (9.12.1P2) with a flexcache volume. Then, a few days later, their jobs are having issues and throwing out "too many open files" error messages. The only change is this Netapp migration. Any ideas? The Linux clients are Centos 7.9.

Thanks,

Steve
