Hello, in history i used kernel 4.2.3 with imq patch (only) for 1 year and it work fine. Before 2 days i installed on same router (debian based) kernel 4.8.4 patched with imq (patch founded in closed issue #46 https://github.com/imq/linuximq/pull/46). After one day router suddenly rebooted (kernel 4.8.4-imq, 2GB ram). The traffic is about 150Mbps. On my graph i see that it use all memory (about 100MB/hour). Router have 2GB of ram. After this first reboot i try diagnose what happen. Router using more and more memory. But no process use the memory!
router6:# ps aux | awk '{sum+=$6} END {print sum / 1024}' 85.8398 router6:# free -m total used free shared buffers cached Mem: 1985 1939 46 0 0 41 -/+ buffers/cache: 1897 88 Swap: 0 0 0
I try many thing to analyse what happen, i cannot find what use the memory. Trying restarting services and still same. Memory is exhausting. When i stop imq with "ifconfig imq0 down", exhausting of memory stop! The current state is that router have 2GB, processes used 85MB and 46M is free, so the kernel use 1917M of memory (2048-85-46)
For all information, i have same kernel on other 3 router (with other hardware), and there is no problem with memory leak or using by imq. Used memory on other router with same kernel (4.8.4-imq) is about 400MB in 2GB RAM. I know, it sound strange. If you want, i can make some other test or append some diagnostic output. I could not experiment too much because router is in network with customers.
