NED building and loading issues

Team,

Recently, with NSO 4.3 and later, I have ran into some issue when building the NED packages and reload them.

For example, when building cisco-ios 5.4.3 with "make clean all", I received "heap allocation error":

eheap_alloc: Cannot allocate 212907632 bytes of memory (of type "old_heap").

The issued on both my VMs with system installation.

I didn't get this error on my Mac laptop with local installation, however, when reloading the packages, I have the following errors:

admin@ncs> request packages reload

reload-result {

package cisco-ios

result false

info --ERROR--

}

reload-result {

package cisco-iosxr

result false

info --ERROR--

}

reload-result {

package delete-preempty

result true

}

reload-result {

package device-report

result false

info --ERROR--

}

reload-result {

package juniper-junos

result true

}

I had to restart NCS a few times, removed all the packages, and only add the one I need at the moment and got "packages reload" work. I cannot imagine if this happens on a customer production server during a NED upgrade.

Does anyone know a valid fix for this issue? Or BU is aware of it and working on a fix?

thanks,

Yang

The NCS JavaVM is hitting the memory ceiling allocated to it. In order to load so many Java packages, you need to increase the ceiling. This was discussed recently here on the Hub. Have a look at this post: https://communities.cisco.com/thread/84613
