#19657: knockd - abnormal memory footprint at runtime
-----------------------------------+---------------------------------------
Reporter: sturia@… | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone:
Component: packages | Version: Attitude Adjustment 12.09
Keywords: knockd ar7 memory RAM |
-----------------------------------+---------------------------------------
Hi,
on an AR7 box (G624t) running Attitude Adjustment the currently available
knockd implementation available knockd_0.5-1 consumes more than 4MB of
main memory, which makes knockd almost useless on low-memory boxes. The
same knockd daemon, compiled outside openwrt and running on another fw
release on the same box, consumes KBs of memory instead of MBs.
Evidences below are from Attitude Adjustment, but it apparently happens
also on Barrier Breaker for brcm47xx.
