Dear all,
I had ASDM 6.2 with ASA 8.2 installed on my pc (windows 7 32 bit). When I launch ASDM process go to 80-90% and my RAM go to 2.5G. when I am looking on the process on the task manager there is a process “javaw.exe” linked with ASDM.
I have done a lot of search on the google/SUN site and forums but I didn’t found anything to resolve this issue.
Have someone had or have some issue with ASDM? Or have you the solution for this issue?
Thanks a lot
Note: I upgraded my ASDM to the latest version 6.4 but still have same issue.

Hi Jazaib,
As other said, you need to find out what was changed. In additional to environment/load changes, extra load could be triggered by suboptimal execution plans due to parameter sniffing and/or stale statistics. For example, you can have the situation when frequently
executed query was recompiled using atypical parameter set and cached plan leads to much heavier I/O CPU activity.
Other factor that often lead to CPU load is bad T-SQL code (multistatement UDF, imperative code, cursors) so check your application.
You can also run the script below, which returns you the information on most CPU intensive queries in scope of the cached plans. Alternatively, you can setup XEvent/SQL Trace sessions capturing statements with cpu_time exceeding some duration.
SELECT TOP 50
SUBSTRING(qt.TEXT, (qs.statement_start_offset/2)+1,
CASE qs.statement_end_offset
WHEN -1 THEN DATALENGTH(qt.TEXT)
ELSE qs.statement_end_offset
END - qs.statement_start_offset)/2)+1) as SQL,
qs.execution_count,
(qs.total_logical_reads + qs.total_logical_writes) / qs.execution_count as [Avg IO],
qp.query_plan,
qs.total_logical_reads, qs.last_logical_reads,
qs.total_logical_writes, qs.last_logical_writes,
qs.total_worker_time / qs.execution_count as [Avg CPU],
qs.total_worker_time,
qs.last_worker_time,
qs.total_elapsed_time/1000 total_elapsed_time_in_ms,
qs.last_elapsed_time/1000 last_elapsed_time_in_ms,
qs.last_execution_time
from
sys.dm_exec_query_stats qs with (nolock)
cross apply sys.dm_exec_sql_text(qs.sql_handle) qt
outer apply sys.dm_exec_query_plan(qs.plan_handle) qp
order by -- or vy qs.total_worker_time desc
[Avg CPU] desc
option (recompile)
Thank you!
