TASK_OS_MEMHIGH on ex2200
Hi,

I am running ex2200-48t-4g with 10.4R1.9 - it was fine for 350 days.

Today my switch started dropping traffic and in logs it says:

Jan 3 05:30:49 ex2200-s1 vccp[748]: TASK_OS_MEMHIGH: Using 50598 KB of memory, 100 percent of available
Jan 3 05:31:49 ex2200-s1 vccp[748]: TASK_OS_MEMHIGH: Using 50598 KB of memory, 100 percent of available
Jan 3 05:32:49 ex2200-s1 vccp[748]: TASK_OS_MEMHIGH: Using 50598 KB of memory, 100 percent of available

It helped to disable port mirroring but i wonder what might be the issue here.

All best,
mjb

It looks like vccpd has leaked a lot of memory. You may drop to the
shell and kill off vccpd, hoping that the switch returns to a working
condition momentarily, rather than freaking out and requiring a
reboot. Personally, if I were you, I would just reboot it anyway. If
you expect multi-year trouble-free uptimes from your switches you made
a bad purchase with the EX-series, and I say that as someone who does
advocate using them for certain things.

That memory leak has been fixed in later 10.4 and 11.1 releases. I have
personally killed the vcpp-task from the shell and JunOS just restarts
the process. There is no ill effect at least what i could observe when I
last did that.
