NAS probe is utilizing more memory near than 2 GB. Every time I need to restart probe to fix it. Any suggestions to investigate and fix this issue.
When the NAS probe memory increase this is often times related to a problem synchronizing the local SQL site database with the back end database.
You can check this by highlighting the nas probe then doing ctrl + P to bringing up the probe utility.
in the drop down choose get_info
under the parameters highlight details and but in a value of 1
then hit the green arrow
scroll to the bottom and you will see nis-bridge and queue_len.
in perfect condition this should be low or 0
if you have 100K + there is a performance issue on the back end database
Things you can do
1) make sure the dba is indexing all tables nightly including the nas_ tables
2) check the nas_alarms, nas_transaction_log and nas_transaction_summary tables and see if they are holding more data then they should be per your retention period in nas setup.
3) deactivate alarm_enrichment and nas then drop the nas_* tables from the back end SQL server then activate A_E and nas and let them recreate.
Hope this helps.
You don't mention your version but on the hotfix page there is a nas release newer than what's in 8.5.1 GA. There are a number of critical fixes in that HF so it's worth applying if your version compatible.
Version is 8.4.

Tech Tip: Alarm Enrichment probe not processing alarms
Went thru a slew of nas issues with alarms stopped flowing and this helped. I now have a processes nas profile setup to keep track of the nas and how much memory is consumes. I never see it go above 300MB.
Add the following nas and hub settings:
Nas:<setup> lower_memory_usage_threshold_percentage = 0.90upper_memory_usage_threshold_percentage = 0.90memory_usage_exceeded_threshold = 3</setup>
Hub:<hub>post_max_age = 60 </hub>
