Winbox 4.x DHCP Lease Lagging

Hi, I have some Mikrotik routers but I see an annoying problem with some of them.

After using new Winbox it is impossible to open DHCP lease. It stuck or lagging. I click on an IP and it responds after 10-15 secs. I though the router has problem, but I noticed same problem in another Mikrotik. Even the Web version is lagging. I try old version (3.41) winbox, it works fine.

I noticed this problem with

CCR2004-16G-2S+ and CCR1036-8G-2S+

What RouterOS version are you using?

Hi, first of all, it's important to mention that without specifying which version of RouterOS you're using, it's impossible to help. Winbox has nothing to do with DHCP. I use DHCPv4 and v6 on Winbox 4.4 and I don't have any problems.

CCR2004-16G-2S+ / 7.24.1 (stable)
CCR2116-12G-4S+ / 7.8 (stable)
CCR1036-8G-2S+ / 7.24.4 (stable)

Thanks for reply. DHCP Lease itself working fine, there is no problem about the function of the DHCP. Problem is if u select IP > DHCP all works fine, but if u click on the "Lease" tab, it starts to lag, to freeze, buttons are untouchable, if u want to click on anything in Winbox window, it responds after 10-15 seconds. I can screen capture it, but not sure if I can attach it here

CCR2004-16G-2S+ / 7.24.1 (stable)
CCR2116-12G-4S+ / 7.8 (stable)
CCR1036-8G-2S+ / 7.24.4 (stable)

What behavior do you experience if you use cli? Can you share output of:

/ip dhcp-server export

You might want to remove static entrees and public IP addresses of present.

ip dhcp-server export.txt (75.4 KB)

I have some scripts here sure thing, but it didn't make any problem with the older version of the Winbox. Now coz I made update of the firmware I can't open it with the older version, so I have to use this new Winbox.

I checked in my CCR2116 with older version of Winbox v3.41 it works fine, same device in Winbox 4.4 freezing

After 1 month of discusses with Mikrotik support, finally they found the problem and fixed in new version 4.5rc2. Just in case if someone gets this problem, I put the links below. Thanks everybody for help.
