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

This is not normal. You could try to run with -vv to see if some error
path is taken that triggers a leak.

Should I look for something specific ?
The log grows pretty fast and it looks like it could contain some
security data which I wouldn't like to post online.
The statistics of the log(about 2 hours) looks like this:
carp_init: 1
config: 7
monitor_get_pfkey_snap: 4
monitor_loop: 1
net: 1
net_connect: 3
net_ctl: 4
net_disconnect_peer: 3
net_handle_messages: 2
net_queue: 91780
net_read: 10
net_send_messages: 39192
pfkey_send_flush: 4
pfkey_snapshot: 6832
timer_add: 19
timer_run: 18
Best regards
