All future XOS maintenance releases will include the fix to prevent the memory resource exhaustion that causes the assertion.
Specifically, this fix will be incorporated into the following versions to be released in the future: XOS 9.6.1, XOS 9.5.6, XOS 9.0.4, and XOS 8.5.6. A system running an earlier XOS release must be upgraded to obtain the fix.
Workaround
Changing TCP/IP socket receive buffer queue sizes on the affected APM module(s) will partially mitigate exposure to this Linux kernel issue. Instructions to adjust the related parameters are below:
-
Login into the chassis and from the unix prompt “rsh” to the related APM:
-
To change the parameters dynamically (takes affect immediately but not persistent through reboot):
-
echo "4096 262144 262144" > /proc/sys/net/ipv4/tcp_rmem
-
To confirm the parameter change:
-
To make the change persistent through a reboot:
-
vi /etc/sysctl.conf - and add:
-
net.ipv4.tcp_rmem=4096 262144 262144
