I have deployed a network of CRS326-24S+2Q+RM working as L3 switch with l3-hw-offloading=yes for better performance.
To use the hw-offloading the CRS326-24S are upgraded to version 7.1rc4
The OSPF routing protocol is used and after deploying the several CRS326 in production environment they began to experience unexpected rebooting.
In our monitoring system the following behavior is observed:
- the used RAM memory slowly increase over time and in a certain moment it reach out of memory and the RouterOS crash and CRS326 is rebooted.
After that we upgraded in our LAB the CRS326 are upgraded to version 7.1rc5.
It helps with some of L3 switches, but one of them still has the issue with the out of memory reboot.
I`ve attached a graph with memory usage.
