We have an account that has close to 950,000 messages in it and is 10+ gb and growing. It was originally for automated processes to sent their logs/output to, but it was not checked for many months and is now super full of messages.
zmmailbox -z -m firstname.lastname@example.org emptyFolder Inbox
and I get:
ERROR: zclient.IO_ERROR (invoke Read timed out) (cause: java.net.SocketTimeoutException Read timed out)
Also, I can't get to the mailbox from the CLI or web GUI now.
