2.9.39-2.9.42 & export command issues on RB112

Hardware MikroTik hardware general
1

I upgraded to the latest 2.9.39 Mikrotik software and discovered that I can not back up the configuration anymore.

The CPU load of the device will go to 100% and eventually the box will fall off the network (most times the hardware watchdog will reboot it, but not always) as soon as I issue:

export file=backup

If to look into the partial backup file the there are some signs of distress:

#error exporting /routing ospf interface
#error exporting /routing rip neighbor
#error exporting /routing rip network

After I disabled non-needed routing package:

#error exporting /ppp profile
#error exporting /ppp secret

After I disabled non-needed ppp package the command was executed OK.

The same issue is with making a supout.rif file.

Is it hardware or software issue?

This seem to be a software issue.

I took a brand new RIC/522 device and upgraded it to 2.9.39.
And this device has the same issue!
This time the config file has following lines:

#error exporting /ip ipsec manual-sa
#error exporting /ip hotspot
#error exporting /system upgrade upgrade-package-source
#error exporting /ppp profile
#error exporting /tool graphing queue
#error exporting /tool graphing resource
#error exporting /tool graphing interface

What to do?

Anyone out there?

You should write to support@mikrotik.com with this issue!

Have you read the http://www.mikrotik.com/support.html?

This e-mail based support is not for everyone to use.

6

what do you mean? if there is a bug, everyone can send it to support. if you are talking about the 30 days limitation, well that is only for configuration assistance or that kind of help. a specific bug report is welcome by anyone.

7

OK, but does this MT forum thread classify as a bug report?

8

No. It’s clearly stated in several places and has been stated by Normunds & Co several times here:
This is a user-to-user forum. To get (“guaranteed”) support from MikroTik, you have to write an e-mail to support@mikrotik.com.

FYI: The 2.9.40 also has this issue.

10

RB112 has very limited resources and that leads to /export failure or slowness.

disable all unneeded packages on this CPE board and you must succeed with export command.

11

So this is a feature?
Are you kidding?
How does the configuration dumping will bring down a system with an 175 MHz CPU and plenty of memory?

12

don’t listen to him, it’s not a serious answer. we are working on this problem.

13

Good to hear.

14

Is there any news about the fix?

15

Even the 2.9.41 has this issue. I have no much hope for the 2.9.42, but I’ll try it out.

Edit: The 2.9.42 is the same.

What does make this issue so hard to fix?
Or does the MikroTik intend not to fix this at all?

Btw: The “backup” functionality is not a replacement for the “export” as it is not human readable.
If the “backup” can be made human readable then I’ll be happy to drop the use of “export” command.

16

On 2.9.42 (x86 only) and a full export I see the following weirdness:

/ system console
set FIXME term=“linux” disabled=no
set FIXME term=“linux” disabled=no
set FIXME term=“linux” disabled=no
set FIXME term=“linux” disabled=no
set FIXME term=“linux” disabled=no
set FIXME term=“linux” disabled=no
set FIXME term=“linux” disabled=no
set FIXME term=“linux” disabled=no

The rest looks okay to me… maybe there is something corrupted in the config and it can’t handle it? Or is this only ap roblem on routerboards?

17

If there is something broken in the configuration then the MikroTik is free to say it and I’ll try to fix it. I can even grant them a permission to access these devices from outside world so they can do all the “magic” by themselves.

Or is this only ap roblem on routerboards?

I see this problem only on RB112. RB153 and RB532 do not have this issue.
