This is likely. I have not used Horde Webmail some weeks.

At first I thought it's a server problem (low memory).

Second I thought, that one of my mail folders is too big. To determine
this I clicked on every IMAP folder in my Seamonkey mail client to see
the mail count. Trash folder has the following setting in my Seamonkey
mail client:

"Delete messages more than 14 days old"

Seamonkey probably has deleted a lot of old trash mails. After this
Seamonkey actions I could login to Horde again.

Greetings,
Björn
