Support Response Time for Reproducible Crash Bug

RouterOS General
1

I created a support case with Mikrotik nine (9) days ago, but it has not received an initial response from Mikrotik. What is everyone’s typical experience with Mikrotik support 1) with respect to response time, and 2) in general? To note, in the ticket I included supout.rif, relevant log entries, and a reasonable description, so it’s not as if it’s a non-actionable support case.

For the curious, I found what seems to be a bug that causes the system to crash and I am able to reproduce the bug.

While adjusting some queue settings, I executed a /queue/type/remove on an existing queue type which was apparently in-use by a simple queue. The command succeeded and then resulted in the system crashing (and continuing to crash upon every reboot). The command should have failed due to validation and not caused the system to crash.

Remote syslog entries such as this occur during the crash:


2025-03-03 10:28:46 system,error,critical router rebooted because some critical program crashed

Local log entries such as this occur during the crash:


Mar 3 10:28:38 system,info queue type removed by ssh:@<USER_IP>/action:<ACTION_ID> (/queue type remove “”)

Thanks for any feedback and/or insight you all can provide!

UPDATE: I reported this issue with the latest (at the time) RouterOS 7.18.1. They released RouterOS 7.18.2 today and it appears the issue is resolved in 7.18.2, at least based on my testing with the CHR arm64 images from both versions :tada: Yay for a fast turnaround time, but there’s still no response on my initial contact in the support ticket :cry:

If anyone’s curious, here are the specific commands issued to reproduce the bug in 7.18.1:


/queue type add kind=pcq name=test pcq-burst-rate=0 pcq-burst-threshold=0 pcq-burst-time=10s pcq-classifier=src-address pcq-dst-address-mask=32 pcq-dst-address6-mask=128 pcq-limit=50KiB pcq-rate=0 pcq-src-address-mask=32 pcq-src-address6-mask=128 pcq-total-limit=2000KiB
/queue simple add name=test queue=test/test target=ether1
/queue type remove test
