ASA High Memory utilization and random lockouts

We have 2 ASA 5520's running Active/Standby with the cable based failover. At random times perhaps once our twice a week we will get calls that RA VPN users cannot connect, RA users connect with the Cisco VPN client. Also most often during this time we cannot telnet into the "primary" ASA, but we can "usually" access it via the ASDM where we will see that the memory utilization is in the upper 90% range and perhaps as high as 98% consistently. To help temporarily solve the issue we have to telnet to the "secondary" ASA which we can usually access via telnet and perform a "failover active" which will failover the primary and make the secondary become the active and vice versus. Has anyone seen this issue. I have opened up several TAC cases and have not had much help. Thanks in advance!

Hi Brandon,
it is important to know what version are running your ASAs [ie 7.0(4)] and to collect some log, you can set it to error level (logging buffered errors), with the logging standby, so all of the message should be replicated on the standby unit.
even the show crashinfo could give you useful info.
show crashinfo

Thread Name: vpnfo_thread_msg (Old pc 0x00b47b80 ebp 0x01c60634)
You can check the caveats for you release from the cisco site, This link is for the 7.0(4)
http://www.cisco.com/en/US/docs/security/pix/pix70/release/notes/pix704rn.html#wp32426
It could be a known bug solved in newer image.
Here you can find useful info to perfom a zer o downtime upgrade.

CiscoWorks LMS 4.0.1 High Memory Utilization on Windows 2K8 R2

Hi,
What causes LMS 4.1 to have high memory utilization?

I made a little batch
https://supportforums.cisco.com/docs/DOC-21031
It show what process in LMS is eating you RAM / Hogging the CPU.
I don't think resources are used very effectivly in LMS
I did have the impression that some virtual machines running LMS 3.2 actually performed better than real machines, as if the VMware saw it load all these java virtual machines and that it was 45 times the same thing only being used for a few % and therefore could be swapped to disk, leaving the resources to what was actually working in LMS.
What worries me more than the resources used is the gui per.formance.
Cheers,
Michel

Windows Server 2012 High Memory Utilization(Three Hyper-V Instance Configure in this Server For Lync)

Hello There,
Issue: High Memory Utilization in Below Scenario. Pl. See the below configuration of Win 12 Server
Pl. see for committed memory bytes . m little bit confused that about committed memory
OS: Windows Server 2012
Memory: Total 24 GB Free:1.3 GB Committed:27.6 GB
App Configure: Three Hyper V Instances Configure For Lync Server 2013
Pls provide me solution on this issue

Virtual memory system. Committed memory is the physical memory for which space has been reserved in the disk paging file. So, you are paging, which is quite common in virtual memory systems.
On a completely different topic. Lync is an application that works best on real cores. Most systems are configured by default to use hyperthreading. Hyperthreading increases the logical processor count on a system and logical processors
are treated equally. Since a hyperthread 'core' (logical processor) performs at a small fraction of a real core (logical processor), if you are running VMs that work best with real cores, it is best to change your BIOS on the Hyper-V host to disable
hyperthreading, sometimes called simultaneous multithreading (SMT).

High memory utilization after few days - ciscoworks LMS 4.0.1

Hello,
I have the problem that our ciscoworks server gets out of memory after few days. The memory utilization is always getting higher an higher (above 95%). Sometimes it is only after 3 days and sometimes it is after 1 week. So it happens not regulary. Has anyone an idea what could be the problem? I have made an screenshot from the services which use a lot of memory. And at this time the memory utilization is getting higher and higher again....I think there is a problem with tomcat or dbsrv10.exe, there are also a lot of cwjava.exe running.
Kindly regards
David Mayer

Hello,
I have the same problem. First time I've tried to upgrade memory from 8gb to 16gb but I am still experiencing same issues (Memory is running on 98%). I'm not sure exactly what process it is causing this issue, because when I've checked all proccesses from all users running on this server and count them there is no 15 gb at all. My guess is the same for tomcat server which is responsible for RME collector, or correct me if I'm wrong.
Do you have any idea what can cause this problem.
I've tried to upgrade then to Cisco works Prime lan management 4.1, but server went with same issues.
Thanks a lot

High memory utilization

Hi,
We have a system(32GB RAM and 2 TB hard disk, Windows7,SQL SERVER 2008R2 enterprise 64 bit). Looks like whenever i run some query(even query result 50 records) on the database, the Memory utilization is very high(30 GB) in task manager. How can i control this
over usage? The memory setting is default in server properties(min 0 and max 2147483647).

Hmm, just curios, do you really have EE installed on Windows 7???????

Cisco ASA 5505 Ipsec VPN and random connection dropping issues.

Hello,
We are currently having issues with a ASA 5505 Ipsec VPN. It was configured about 7-8 months ago and has been running very well..up until the last few weeks. For some reason, the VPN tends to randomly disconnect any user clients connected a lot. Furthermore, sometimes it actually connects; however does not put us on the local network for some reason and unable to browse file server. We have tried rebooting the ASA a few times and our ISP Time Warner informed us there are no signs of packet loss but still unable to pinpoint the problem. Sometimes users close out of VPN client completely, reopen several times and then it works. However it's never really consistent enough and hasn't been the last few weeks. No configuration changes have been made to ASA at all. Furthermore, the Cisco Ipsec VPN client version is: 5.0.70
Directly below is our current running config (modded for public). Any help or ideas would be greatly appreciated. Otherwise, if everything looks good...then I will defer back to our ISP Time Warner:

WebLogic JMS high memory usage and frequent full GCs

Hi Team,
            We have below set up in production (and all the lower environment).
1. WLS: 10.3.6 (64 bit)
2. Java: HP JDK 1.7.0.06 (64 bit)
3. Two Manage server instances in cluster with one Migratable target
4. one JMS server with Persistence store targeted to Migratable target
5. Messages are persisted in DB
6. about 37 distributed queues/topics are hosted on one JMS server
7. .Net JMS clients and WebLogic JMS clients connect to respective JMS distributed Queues/topics to either produce message or consume.
Since last month, we see that WebLogic Manage server hosting JMS server keeps on chewing memory "even with small (of the order of 28 messages in 4/5 days) load", GC indicates that objects are shifted from PSYoung space to ParOldGen during minor GCs but ParOldGen space keeps on filling up in smaller chunks. After x number of days (where x ranges from 5-7 days), even Full GC is not able to bring down memory significantly and that's when frequent full GCs start with long pauses making JMS highly unstable.
We don't have JMS Quotas configured but I think something else going on as it is not high on load. Any additional hints or troubleshooting steps is much appreciated?
Here is first and last GC log just to give an idea...

Regards,

Thanks Luz. I have been collecting gclogs and heap dumps (whenever app server is high on memory and frequent GCs with long pauses are seen). So far heap dumps haven't revealed anything specific (may be I am not able to read heap dumps properly ) but looking at GC confirms that app server is consuming allocated heap.I was following Oracle WebLogic server support Patter as you have indicated. I thought about opening a ticket with HP but on high level JVM is doing what is suppose to do i.e allocating memory space as needed and performing GC therefore didn't go that path.
Any other suggestions that might be useful. One of the things I forgot to mention ( and I will add it to original message), that one of the .Net consumers is not asynchronously connecting to its queue (to consume messages) rather it is synchronously connects and then if it doesn't find messages it disconnects and process goes on every few seconds. I was reading somewhere that frequent JNDI look ups should be avoided. Can this cause memory issue if so then it is strange as this same set up has been there over a year and we never has problem then?
Regards,

High Memory Usage and a few other problems

I install Oracle DB 11g R1 into a Window 2003 Server virtual machine (VirtualBox) running on Ubuntu Linux. I did just a "plain jane" install accepting most, if not all, the defaults. When I start the service though, the Mem Usage shoots to @ 400 megs and there are several java.exe's that are also running each with anywhere between 80 and 130 megs. Plus, its seems that they never seem to 'settle'; Oracle.exe and one of the java.exe's are always taking up basically 100% of the processor.
This is just CRUSHING my poor little machine.
Any way to throttle these guys back? I can reinstall if needed. Its not like I've done much with it yet.
Thanks!

Your 400M seems quite lightweight - probably based on a VM allocation of 1GB. You are starving the poor thing. You possibly missed this section in the Install manual before you did the install (http://download.oracle.com/docs/cd/B28359_01/install.111/b32006/reqs.htm#i1011417)
The database instance itself wants between 500M and 750M for the SGA for a minimum 'properly functioning' system.
Any user connections will want roughly 30-50M / connection, although that can vary wildly.
Enterprise Manager (DB Console), being Java (JEE) based, will gobble as much as you give it, and then some.
If you want to cut back, turn off the EM DB Console. If you do not want features, you could always perform a separate CUSTOM dbca creation without Java in the database and there are several other features that you could toss. 11g could probably limp along with as little as 350M. (You seem to be in the limping-along arena.)
And yes, the internals to Oracle Database do dictate fairly significant memory, CPU and disk (esp bandwidth) utilization. Your poor machine is being crushed because you have mismatched it to the load.

Resolving ASA high memory issues

Hello,
I have an issue of high memory usage in my ASA5540 (85%).

I suspect that the issue is caused by 65536.
Below the result of the command "show memory binsize 65536"
I think the issue is caused by the pc 0x092acca2, how can i decod it?
How can i resolv my problem?

Agent resident memory utilization and Agent Virtual Memory Growth is HIGH

I have been receiving many alerts from EM on agents resident memory and virtual memory growth is high. Every time the agent is getting restarted by watchdog.
I am wondering where exactly the problem is ...!

What platform and what Agent version are you using?

High memory usage and error creating access rules

Hi guys
I'm having a problem with the memory and also trying to create some rules on the CISCO ASA. The version that I got installed was the 8.2.5.33 on a CISCO 5520 with 512 RAM, the memory usage is on 99% used, 1% free and because of that when I'm trying to create a new rule the firewall brings me the next error
So what I did was a downgrade to the version 8.2 (4) 4 and the memory went down a little (82% used, 18% free) but I still got the error when I'm creating an access rule on the device. One thing and I'm not sure if this could affect on the performance are the number of access list and the object groups that are created.
I already open a case with CISCO TAC and they are checking if the problem is with the memory capacity or maybe a memory leak.
Also the doubt that I got is with the memory that I got now available should I can create access rules or 82 is still to hig to create a rule or and object group?

Hi,
Can you check what is the amount of ACEs you have on the ACLs in use?
I think if you use the command "show access-list " the first line should give you the total amount of ACEs in the ACL

High Memory utilization for a single project

Hi All,
I am facing one issue with one of the projects configured. We have endeca installed on a Windows server and there are multiple projects setup. I am observing that dgraph.exe for a single project is taking as much as 80% of memory on server. I do see that the project is receiving around 300 to 350 requests every day which is slightly higher than other projects. I am required to manually restart the project before business starts and that releases the memory. I am not able to identify whats causing this issue. Any ideas on how to troubleshoot the issue?
Any suggestions will be of great help..
Thank You,
Sunil

The number of threads will not have any impact on memory usage, however, I agree with Saleh that this doesn't make any sense.
I would suggest the following:
Grab the stats page XML (http://[your server name]:[your port]/admin?op=stats).
Restart the dgraph and see how much memory is taken up on the initial load. Then, assuming the memory consumption is reasonable, issue a couple N=0, N=something queries to the index and track what's happening with how much memory is being taken up.
If you're still at a normal level, it seems like there must be some process or "bad query" that causes the memory to spike. A possible culprit might be found on the "most expensive queries" section of the stats page but it's possible it won't be there as that only tracks queries that have completed, not queries that are still in process or taking forever.
The only other explanation I can think of is a rogue "bulk export" query where a user is trying to (for example) export the entire index to excel or something like that. Does your application offer that functionality?

High circuit utilization and WAAS

We have been experiencing some issues that I think are related to the WAAS and need opinions and advice on how to resolve.
We are running the latest 4.1.1c code on all WAEs and are running in the new AO mode (not file services in legacy mode).
At our data center (where the servers are) we have a 9mbps circuit connecting it to the MPLS cloud. At some of our remote sites (where the users are) we have T1s and fractional T1s. Almost daily we are seeing cases where a single connection is consuming all of the bandwidth at the remote sites. This is typically only for a defined period of anywhere from 10 minutes to an hour and can be traced to particular activity like copying a large files, etc. Before the WAAS was implemented we wouldn't see cases where a single operation could consume literally 100% of the bandwidth and I wonder if the core WAAS (at the data center) could be over utilizing the bandwidth since the core has 9mbps available.
The problem is that when this occurs, it affects everyone else on the circuit since the circuit is slammed. Most of our users use terminal server connections and theses are greatly affected when all of the bandwidth is consumed. We have given the terminal server connections a higher priority inside the WAAS (through policy prioritization) and setting the DSCP marking to af21(18). We have even tried QOS on the routers but the condition occurs on a regular basis.
Please help!

See the attached. It provides a very good overview. Is the adaptive buffering enabled?
If not, either way a TCP window of 512K allwos the WAE to burst segments upwards to 512Kbytes. You want to be able to utilize the link to maximum capacity to compensate for latency. Howeve rif smaller apps are being choked then need to be adjusted. I am suprised that Q0S on the router had little effect ont he smaller traffic sessions.

Query for finding Oracle CPU and memory utilization and

I want to gather the report using Oracle views in the same formatas of the report which the top utility gives for Sun-Solaris OS processes.
I want the same type of report for Orcale database processes including all the user processes and the oracle internal processes.
can any body tell me if it is possible.
I am writing the top utility report format below and its contents:
CPU-processor number
TTY-Terminal interfaces used
PID-Process id number
USERNAME-Name of the owner of the process
PRI- Current priority of the process
NI- Nice value
SIZE- total size of process (text+data+stack)
RES-resident size of process
STATE- current state of process
TIME-number of system and CPU seconds the process has consumed
%WCPU-weighted CPU
%CPU-raw CPU
COMMAND- name of the command
thanks in advance

How to display CPU and memory utilization from ST06 in a report

Hi,
I want to display CPU Utilization and Memory utilization and File sys details from ST06 transaction in a report.
Is there any function module or any other method to do that.
Please advice.
Thanks,
Sandeep.

Hi Ranganath,
Thanks for your time.
And thank you very much for the reply.
Both the function modules are helpful.
But can u also help me in getting the data of FileSys from ST06.
Thankyou,
