Hi, I recently use the ASAN feature with gcc on our custom binary using NMSDK 9.7, and it detected such memory leak: Indirect leak of 128 byte(s) in 2 object(s) allocated from: #0 0x7f963768fb50 in __interceptor_malloc (/usr/lib/x86_64-linux-gnu/libasan.so.4+0xdeb50) #1 0x7f962e858da5 (/lib/x86_64-linux-gnu/libc.so.6+0x103da5) #2 0x7f962e85a0a6 in getaddrinfo (/lib/x86_64-linux-gnu/libc.so.6+0x1050a6) #3 0x7f963764825a (/usr/lib/x86_64-linux-gnu/libasan.so.4+0x9725a) #4 0x7f962f42c5c5 in na_server_invoke_elem_http /libnetapp/na.c:3575 #5 0x7f962f42b6c9 in na_server_invoke_elem /libnetapp/na.c:3014 #6 0x5593aea874e8 in NetAppApiClient::InvokeAPI(int, ScopedNaElem*, ScopedNaElem*) (/tmp/netapp_api_client_main+0x49e4e8) This is consistently being reported when the API above is called. Looks like the memory allocated in getaddrinfo() is not freed (check https://man7.org/linux/man-pages/man3/getaddrinfo.3.html, there needs freeaddrinfo() afterwards). Is this a known issue? The fix seems to be straightforward if this is confirmed a legitimate memory leak. By the way, is the netapp SDK source code public (and people can make contribution to)?

Hello, we're trying to deploy and install a CA-signed ssl certificate on the admin vserver to get HTTPS when connecting to the cluster webgui. With the netapp.ontap.na_ontap_security_certificates module we have successfully deployed the certificate on the cluster, but it will not be used by the vserver. We somehow need to execute this command. security ssl modify -vserver [VSERVER] -serial [SERIAL] -ca [CA] Is this possible without using the na_ontap_ssh_command module? https://docs.ansible.com/ansible/latest/collections/netapp/ontap/na_ontap_security_certificates_module.html#ansible-collections-netapp-ontap-na-ontap-security-certificates-module

Hi All, I am hitting a crash inside NMSDK. Scenario: After successful "na_server_open", when "na_server_invoke_elem" is done, the call fails with error “[13011][unknown address format.]”. After this, when "na_server_close" is done, the process crashes inside NMSDK. I think somewhere the connection is getting dropped and NMSDK is releasing the "na_server_t" object created as part of "na_server_open" which is causing the crash. #1 0x00007f28db62be26 in pool_internal_free (ptr=0x7f2800000001) at pool.c:703 #2 0x00007f28db62b8ea in pool_free (p=0x7f28db9fb5e0 <pool_global_data>, ptr=0x7f2800000001) at pool.c:404 #3 0x00007f28db79a110 in na_server_close (s=0x7f289803c360) at na.c:1092 Any thoughts/ideas/suggestions are welcome.

Hi all, I've written a .NET Console app that imports in data from CloudInsights into our SQL database. It's making about 80,000 HTTP requests to the API that are throttled to no more than 50 consecutive requests. Once in a blue moon on a Friday the thirteenth, I get the following error response to all of my requests related to Vmdks: https://xxxxxx.xxx.cloudinsights.netapp.com/rest/v1/assets/vmdks/3686379087605277227/performance?fromTime=1627302704044&toTime=1627303064044 Method: GET, RequestUri: 'https://xxxxxx.xxx.cloudinsights.netapp.com/rest/v1/assets/vmdks/3686379087605277227/performance?fromTime=1627302704044&toTime=1627303064044', Version: 1.1, Content: <null>, Headers: { X-CloudInsights-ApiKey: XXXXX } { "errorCode": "NOT_FOUND", "errorMessage": "Could not find virtual machine disk for id: 3686379087605277227" } When I test out this request in Postman, it would appear that no Vmdk with that ID even exists. Any idea why the API would occasionally return Vmdks with IDs that don't map to anything? It's a very infrequent issue and only occurred maybe 3 times in the 150+ times I've run this program. What's strange is if I immediately rerun the program, it will have no issues. It happens so infrequently that it's not a massive issue, but it still something I'd like to resolve. My program runs hourly and if an execution fails for an hour, that hour's data will be missing. Thanks for the help!

I work for ISV and I develop an application that integrates with netapp ontap apis to collect information so that our customers can use our application with their netapps. We have deployed ontap select virtual appliance to develop but after 30 days it stop working and have to redeploy new one. Is it possible to get a permanent free license to develop against netapp ontap select virtual? if so where should i ask for it?
