controller reboots when blacklist reaches 300

Hi all, have an old controller running 5x software.  It reloads itself when blacklist gets to 300 entries.

 

Any ideas ??

 

Thanks

You should open a support case.  That should not happen.

Colin, indeed, problem is controller out of support, just seeing if anyone had seen the issue.

Re: controller reboots when blacklist reaches 300

How is the blacklisting being done?

What version of ArubaOS?

What controller platform?

Colin, its an old 6000 controler (well 2 x 6000), master local, running 5.0.4.13 firmware.  Blacklist clients in the local are showing as 'user defined' but blacklist clients is checked in the VAP profiles.

 

The local controller has no issues, same box, same firmware.  It has blacklist clients there 200 days etc ....

Type "show version" on the box to get the reboot reason.

up 42 days, last reboot: user reboot

 

I have seen the 'user reboot' before in other issues where the controller has self-booted

Stunshot, is it running on SC hardware then in late 5.0.4.x on SC1/SC2 will be very low on memory during run time if the number of APs is high, such as around 100 and over. It's possible it's running out of memory, in which case there are not a lot of options.

 

Can you show output of "show memory" while this controller is in runtime, can also show "show memory debug" as an attachment too.

Re: controller reboots when blacklist reaches 300

Hi stunshot

 

Total 256060, used 252069, free 3971

 

Once you are down under 10M free, you are at risk of going out of memory for any number of reasons, including:

 

> sudden influx of users (special event, open day etc.)

> tar logs techsupport -- for your current free memory, i would outright ban the use of tar logs tech.

> more APs coming online

> sudden change in WMS data (which causes on board database to grow, thus size in memory) - in fact this applies to anything in the database, including the blacklist users.

 

This controller is only "just" stable - if there is anyway you can deload it a little that may be a good idea, in a master/local the local may be a little more free since it's not handling the WMS data, you could possibly load it slightly higher.

 

please note that deleting the flashbackup file won't have any bearing on this, so you can just leave it.
