[Pki-users] Slowness and java.lang.ClassCastException

Hi. I am running a DogTag server as part of a FreeIPA install. I have an issue which has persisted following some directory replication issues, now resolved. I had initially put the slowness down to the replication issues but now I find errors in the PKI logs and the slowness has persisted. Though the services are working as intended, it's very slow and in particular the API is sitting at 100% load (user) while performing operations. Extracts from the logs are pasted at https://paste.fedoraproject.org/paste/7pz2eBm6KzItXZFFoYpldQ I'd be very grateful for any guidance as to how to investigate further. Thanks!
