WebUI always crashing and slow
Hello all,
We've been encountering numerous instances where GUI page would be very slow to load and sometimes lead to crash. Workaround is always restarting the tomcat httpd services but frequency has been increasing recently. I have a SOL article pointing it memory leaks to be the case but it was also stated in there that it was already fixed in 11.4.0. We are currently in 11.6.0. Anyone experiencing same issue>

What is your memory usage if you look at statistics?
Can you see the memory usage climb over time? Do you use tmsh as default shell for users? That could be a real memory hog.

Hello Patrik,
I compared the usage of this unit with other boxes and I see that it does have unusually higher usage. System Memory Other is at 50%.
Other is usage of processes other than the TMM. Can you paste the output of
, presstop
and theno
(note the capital Q)?Q

Send the output of this command too?
ps aux | awk '{if($6 > 10000){$6=$6/1000 " MB";print $6 " " $11}}'
Please use the pre-formatted option in the forum (mark the text and hit CTRL + k). It's easier to read.

What is splunkd doing there? :)
/Patrik
Please return the output of
,ls -al /opt
andwhich splunkd
?find / -name *splunk*
Never seen splunk installed on an F5 before. Maybe someone else has?

I have no idea to be honest, but other units have it too but not experiencing the same problem.
Also, for fun, can you run
? Replace with the one found in the PID column of ps aux.pfile
This would show which files it has open.
