Looks like there is no life in MT kingdom after 6.40.5 and 6.41rc52 - see no changes on download page for days. Hope to see another 6.40.x current before we see “6.41-Revolution-is-here” release!
increase in cpu usage to 16% from 1% on RB3011UiAS
I’ve also noticed a slight cpu (not as much as yours) increase on CCR1036 after upgrading to 6.40.5 from 6.38.x.
CRS317-1G-16S+ switch menu shows no ports is this normal?
6.35.4-------->6.40.5 with ease.
Hi all
I have the exact same problem after upgrading my RB951G-HnD to 6.40.5. It beeps every 6 seconds. It doesn’t get picked up in Netinstall. Also, Windows cannot keep a LAN connection to the RB, it keeps on Identifying and then cable unplugged (loop). This occurs on all ports. Is there any solution to get my RB working again. I have done a reset as well with no success.
Any advise will be appreciated.
Regards

On RB433AH updated from old 6.39.2. It works good but something may be wrong with DHCP6Client.
6.39.2 got address and prefix from my ISP in few seconds.
6.40.5 got nothing and searching forever.
I downgrade to 6.39.3 and problem still the same.
So finaly downgrade back to 6.39.2 and it works fine.
So IPV6 implementation of my ISP may be buggy. Or something wrong with new 6.39.3 to 6.40.5 release.
Can i solve this when i reset RB to default and setup it again from backup ?
So I upgrade it to 6.40.5 and reset it to default. Then I setup it from backup and it works fine. So best way is BACKUP → UPGRADE → RESET TO DEFAULT → SETUP IT FROM BACKUP.
I had problems with several Samsung Galaxy S7 Edge devices running Android 7.0 with wAP AC and central CAPSMAN controller running 6.40.5. The smartphones connected, but they had no internet. I updated the wAP AC from 6.40.5 to 6.41rc56. The CAPSMAN controller is still runing at 6.40.5
Now the smartphones can connect and have internet access. So whatever change the latest RC received it would be great if that one could be integrated into the next 6.40.x release.
Last current has a problem about MTU.
Since I run MPLS I had a problem with a client that has VPLS flapping, after a lot of time throubleshooting I run a ping with don’t fragment bit and packet size 1526 and despite the MTU and L2MTU of interfaces were 1600 and MPLS MTU 1530 it fragmented, so I raised to 1700 the L2MTU and it worked. Before the update I haven’t had this problem on any network with same configuration.
after upgraded to 6.40.5 make increase cpu activity sometime always hit 100% usage
rb750r2
rb750gr2
rb450g
rb850gx2
edit: replace rb750r2 & rb750gr2 to rb750gr3, rb450g to rb850gx2, rb850gx2 to ccr1009-7g with same config currently look fine
i think the old hardware doesnt powerfull enough passing high bandwidth
Updated 2011UiAS-2HnD from 6.40.4 (firmware 3.41) to 6.40.5 - so far no problems.
Upgraded my CHR(Dude Server) to 6.40.5 and now the Dude server lost all SVG icons for devices, the background grid map doesn’t show and adding it back I get stuck in ‘loading’ but the images don’t show.
Device discovery completes but the topology does not resolve. 1 hour later, still stuck at ‘finishing 100% Complete’.
PPP profile ‘on-down’ commands are run when connection attempts unsuccessful.
We run a simple script to clear connection tracking entries, so that NAT updates correctly when outbound connectivity for VoIP changes. Primary connection is PPPoE and failover is LTE.
Problem is that PPPoE client, when connection attempt times out, always runs ‘on-down’ commands, instead of only running them if the state changes.
The script:
/sys script
add name=clear_voip_conntrack owner=admin policy=read,write source="/ip firewall connection remove [find dst-address ~ \":4569\"];\r \n/ip firewall connection remove [find dst-address ~ \":5060\"];\r \n"
PPP profile:
/ppp profile
add change-tcp-mss=yes name=voip-reset-conntrack on-down="/sys script run clear_voip_conntrack" on-up="/sys script run clear_voip_conntrack"
/interface pppoe-client
add interface=ether1 keepalive-timeout=60 name=ADSL password=***** profile=voip-reset-conntrack user=user@realm
‘/sys script print brief’ will show run count incrementing when connect attempt to establish but times out…

Dear Mikrotik Team
A DoS vulnerability has been released to RouterOS 6.40.5.
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-17538
https://www.exploit-db.com/exploits/43317/
What kind of schedule is correspondence such as update?
Best regards.
That is not a vulnerability. Somebody made a ping script that floods the device, and result is that CPU usage rises.
Any task will affect CPU usage. This is normal.
The submitter is some person looking for internet fame.
We will see who we need to contact to de-list fake CVE submissions.
Thanks normis.
Was there any such circumstance in this information …
For the time being, I will try to keep this situation still.
Best regards.
