Hello,
=20
I am running snmpd 5.4.1.2 built from a port on 7-Release, hardware is
Sun V100, 512Mb total memory, 381Mb free. The daemon starts fine. When a
snmpwalk is done from another system all is well until the interface
table and then I see:
=20
interfaces.ifTable.ifEntry.ifSpeed.1 : Gauge32: 10000000
interfaces.ifTable.ifEntry.ifSpeed.2 : Gauge32: 0
interfaces.ifTable.ifEntry.ifSpeed.3 : Gauge32: 0
snmpwalk: No response arrived before timeout.

After the timeout happens, looking at "swapinfo -k" shows that swap
space is continually consumed until empty at which point the snmpd
daemon is stopped:
=20
fbsdh# swap_pager: out of swap space
swap_pager_getswapspace(16): failed
Nov 25 11:44:08 fbsdh kernel: pid 84674 (snmpd), uid 0, was killed: out
of swap space
=20
Now the swap space is freeded:
fbsdh# swapinfo -k
Device          1K-blocks     Used    Avail Capacity
/dev/ad0b         2099160    26456  2072704     1%
=20
Has anyone seen this issue or know of a solution.=20
=20
Thanks for your assistance,
Steve
