Hi all,
We have a triple redundant vpn gateway setup with sasyncd running and
tons of tunnels, about 1000 flows.
Looking at the graph of memory usage, you can clearly see that something
is sucking up the memory.
The graph can be viewed here: https://pasteboard.co/I4sjzQ8.jpg
Looking at the ps, sasyncd shows huge memory consumption:
USER PID %CPU %MEM VSZ RSS TT STAT
STARTED TIME COMMAND
_isakmpd 33560 0.0 17.0 699264 708508 ?? S
26Feb19 6:58.81 /usr/sbin/sasyncd
It only happens on the master node. Slaves do not show such a behavior.
There is nothing about sasyncd in the logs.
After sasyncd restart memory consumption is minimal, but tends to grow.
Is it normal ? or am I missing something ?
Best regards
M.K.
