Cisco Unity Connection cannot accept new messages,

Cisco Unity Connection cannot accept new messages, and you may not be able to upgrade Connection.

What is your actual question? IMHO The message is quite clear, the storage where you have your messages is full and you'd need to clear up space on it.

realy i deleted all messages and still have the issue .

Cisco Unity Connection cannot accept new messages, and you may not be able to upgrade Connection. The location where messages are stored has reached the maximum capacity specified on the Disk Capacity page. You can still send broadcast messages. Instruct Connection users to immediately delete unneeded voice message, and wait up to 30 minutes for the CleanDeleteMessages task to remove deleted messages from the hard disk.

It’s possible you only deleted the messages which move the messages to the Deleted Items folder rather than permanently removing them. Modify the Message Aging Policy to ensure messages in the Deleted folder are permanently deleted, by default it set for 15 days.

Alternatively, you can use the Bulk User Delete option to clear user's mailboxes, which will also free up the space.

As both @Roger Kallberg and @Nithin Eluvathingal mentioned, you'll need to examine your disk usage more closely. Ensure you have a message aging policy created that is purging messages at regular intervals, and applied to users via their assigned Class of Service. The first place you'll want to check is under Connection Administration>Message Storage>Mailbox Stores. There you'll find your mailbox stores, I would expect you'll see yours over quota. You could temporarily increase the "Maximum Size Before Warning" but if you don't manage the system with aging policies, you'll just fill that new space up and be in the same situation.

If you need to manually run the tasks you can force them from CLI below. Otherwise, you can schedule and run them from the GUI under Connection Administration>Tools>Task Management. "Clean Deleted Messages" and "Message Aging" are the ones you'd be looking for. If you clean each task, you'll also see the task execution history and if there's been any failures to be aware of.

If you force them from CLI, they'll need to be executed on the server running as "Primary" role in the cluster otherwise the command fails with something like:

The value of 'task_name' is not valid or 'task_name' is Singleton
USAGE: run cuc sysagent task task_name
Command failed

run cuc sysagent task Umss.MessageAgingTask (this one assumes you have an existing message aging policy configured and applied to users)
run cuc sysagent task Umss.CleanDeletedMessagesTask

I would consider opening a case at this point.

What do the outputs of the following look like?

What is your Disk Capacity value set to? By default it is 95%, but did somebody change it to something lower?

System settings - Advanced - Disk Capacity

it's already 95%

Brad Magnani — Thu, 27 Mar 2025 16:57:39 GMT

The CLI outputs look ok. As @Andrew Skelly mentioned, what does the Message Storage>Mailbox Stores page look like? Then if you click on your individual mailbox store(s), what does that look like?

Re: Cisco Unity Connection cannot accept new messages,

Brad Magnani — Thu, 27 Mar 2025 19:49:02 GMT

I did notice in your "show status" output however, your system is running at 100% CPU load since CPU Idle is 0%.

CPU Idle: 00.00% System: 14.47% User: 05.07%

You many also want to run show process using-most cpu and see if it gives any clues. Otherwise, I would suggest opening a TAC SR to figure out what's going on with your server.

Where you able to figure out this issue? I have exactly the same symptoms.
