I need to make one clarification in the recommendation to move to 9.2.1 for the memory leak solutions.
Spectrum memory growth/leaks are the most challenging issues for us to debug and solve, and until we know through debug and data collection what is causing the leak or growth, we have no way of knowing if what you are experiencing will be fixed in 9.2.1 or not. -- Rene' René Cantwell CA Technologies Support Delivery Manager Tel: +1-603-334-2497 or +1 877-428-6324 Fax: +1-603-334-2540 [email protected] <mailto:[email protected]> <javascript:ClickThumbnail(76)> From: Cantwell, Rene D Sent: Wednesday, August 31, 2011 1:00 PM To: 'Mark Serencha'; spectrum Subject: RE: [spectrum] Memory issue Good to know, it would appear something was added or changed in the database between Thursday and Friday. Have you been able to gather any additional details? These are all the SpectroSERVER memory issues fixed in 9.2.1. In addition there is a search caching functionality has been adjusted so that caching is not happening every 10 minutes. Your memory problem could be a combination of any of these scenarios or triggered by just one. Could any of these apply to your scenario Mark? Symptom: SpectroSERVER is leaking memory when 'WriteAttribute' or 'WriteAttributeInstance' event procedures are used. Resolution: Memory is freed correctly when the procedures mentioned above finish writing the attributes. (9.2.1, dvbug019547) Symptom: SpectroSERVER and SecureDomainConnector memory growth and instability. Resolution: Eliminated memory growth and improved code stability. (9.2.1, swbug024587, 19807054-1) (9.2.1, swbug024613, 19848990-1) Symptom: The Trap Director SS grows in terms of memory usage. Resolution: Fixed a memory leak in the Trap Director functionality. (9.2.1, atest011081) Symptom: A memory leak is observed over time in the context of performance data collection on multicast models. Resolution: No memory leak is observed any more in the context of performance data collection on multicast models. (9.2.1, dvbug020171) Symptom: A small memory leak is observed upon multicast discovery Resolution: No memory leak is observed an more upon multicast discovery (9.2.1, dvbug020175) Symptom: Memory used by SpectroSERVER keeps increasing over time when traps are permanently being received from unmodeled sources in a DSS environment with trap director enabled. Resolution: Memory used by SpectroSERVER won't keep increasing over time when traps are permanently being received from unmodeled sources in a DSS environment with trap director enabled.

The SpectroServer was shut down cleanly, but it would not restart properly; it would crash in the manner you describe during SSDB model loading. We reverted to a Thursday backup of our SSDB (the Friday backup had the same problem) and are still investigating. At this time, we are uncertain if some landscape changes added on Friday contributed to this problem or not. We have downloaded 9.2.1, but we have not evaluated it yet.

You can review the release note for 9.2.1 where it will list out the brief details of all solutions. To find the solutions for memory leaks just do a search for the word "memory". -- Rene' René Cantwell CA Technologies Support Delivery Manager Tel: +1-603-334-2497 or +1 877-428-6324 Fax: +1-603-334-2540 [email protected] <mailto:[email protected]> <javascript:ClickThumbnail(76)> From: Jeremy Montoya [mailto:[email protected]] Sent: Wednesday, August 31, 2011 12:19 PM To: spectrum Subject: [spectrum] Memory issue I currently am running 9.2 with H04 and am finding that the SpectroServer.exe process is increasing to 2.5gb of first virtual memory then physical memory and I receive two alarms that the max threshold has been reached. Shortly after the Spectro Server crashes and I lose the landscape. Has anyone experience this at all, possible memory leak? * --To unsubscribe from spectrum, send email to [email protected] with the body: unsubscribe spectrum [email protected] * --To unsubscribe from spectrum, send email to [email protected] with the body: unsubscribe spectrum [email protected] --- To unsubscribe from spectrum, send email to [email protected] with the body: unsubscribe spectrum [email protected]
