NWMKDE using too much memory(abend)

Hello, I have a Netware 6.5 sp7 server with 4gb of RAM. It runs GW MTA, GWIA and WebAccess and NO Backup software. but lately, when I restart the server it reboots it self a couple of times and I notice memory allocation errors. When it comes up Java and apache won't load so I have to manually start it. I ran SEG and NWMKDE.NLM is using almost 800mb of RAM!! so I was thinking on set thinkingMergeSortBufferSize=0 to 307200 so it does not use up to 60% of total RAM. Is this correct? any ideas? can i set java or apache to use less memory?
Thank you in advanced
Ramiro

  • OIM 11g using too much memory and not releasing it when shutting down

    Hello,
    we have a problem with OIM 11g using too much memory (about 5gb) and it's not releasing it at shutdown (4gb still used).
    We are using a VM with RedHat Linux 5.6. Originally we had 4gb RAM + 2gb swap file. We installed Admin Server, OAM, OIM and SOA on that machine but quickly realised we couldn't run all 4 programs at once in 6gb. AdminServer could run with 2 other products, but it was a tight fit in memory.
    So we increased the RAM to 8gb (still 2gb swap file). But then our problem occured : I start the Admin Server (2.7gb total memory used), then OAM (4.6gb total memory used) and then OIM. After it started the server is now using 9.6gb of memory (~300mb of free memory) ! The problem gets even better : after I shut down everything (OIM, OAM, admin server) the "top" command show that there is still 4gb of memory used even tho nothing else is running on the server ! There is absolutely no other process (other than root stuff) running and no other users connected to the machine. After a reboot, it shows 400mb of memory used. I tried restarting the programs and it did the same thing.
    Our intuition is that there might be a memory leak or some bug in OIM that might use up almost all the free memory and it's not releasing it upon shutdown. It might have been there before we increased the memory but have not noticed it since memory was already tight.
    Anyone encountered the same problem ? Any idea ? Any suggestion to narrow down the problem ?
    Thank you

    You can adjust the memory settings for WLS by editing the setSOADomainEnv.sh file that can be found in your /middleware/user_projects/domains/<domain>/bin/ folder. There is an argument called PORT_MEM_ARGS which is used to set your Java memory arguments. This way you can decrease/increase the amount of memory used by each managed server.
    I usually type "ps -ef | grep oracle" to see what processes are running by the oracle user. This way the output doesn't get cluttered with root processes.

  • Every time I load my igoogle home page opening firefox, it opens it in two tabs instead of one, and then AVG tells me firefox is using too much memory and I should close and reopen it; Why

    I open firefox using my igoogle home page and immediately it opens two igoogle tabs on top instead of just one how do I stop it from opening the second one? and then after about two minutes AVG tells me firefox is using too much memory slowing my machine and tells me to close and reopen fire fox...how do I fix that?

    Make sure that Firefox closes properly and that that there are no longer Firefox or plugin-container processes left on the Processes tab in the Task Manager. Otherwise session restore will reopen the page(s) from the previous session.

  • Why does Firefox keep telling me that it is using too much memory, (eg: 235MB) and I should restart Firefox?

    Lately Firefox has been popping up a warning while I am on the internet saying, that "Firefox" is using too much memory. It suggests shutting down Firefox and restarting Firefox. It also told me how much memory that is in use at that time. It is usually about 235MB or more. What is normal memory use for Firefox to use while I am on the internet? Does high usage mean that some other person is trying to get into my computer?

    You appear to have AVG installed:
    *See --> http://forums.avg.com/ww-en/avg-forums?sec=thread&act=show&id=173969#post_173969
    From reading on the internet, it appears that when there is a spike in memory usage, AVG "interprets" that as a memory leak, possibly caused by malware. AVG could be incorrect concerning that assumption. Maybe they are being a bit too conservative about memory usage; just my opinion.
    The decision is yours to turn off the "advisor" or leave it on.

  • I am warned on 2 computers that Firefox 7 is using too much memory

    I am warned on 2 computers that Firefox 7 is using too much memory.. one is running windows XP the other is Windows 7. Both have substantial memory
    this started after updating to 7.0.1

    yes when you download AND INSTALL a new version the previous one removed

  • Why does AVG keep telling me Mozilla is using too much memory?

    Why does AVG keep telling me that Mozilla is using too much memory and I have to close and reopen the program?

    the Advisor is just telling you the same thing you can see for yourself in the Task Manager; I can open firefox with only a few tabs and then watch the memory usage skyrocket when Firefox should be doing nothing - after a couple of hours it will get up to as high as 1.5GB before it completely hangs and I have to end the process in Task Manager, and this does this with all extensions disabled and in Safemode.

    Mavericks uses RAM much more efficiently than any other previous version of OS X. Mavericks now has a memory compression feature that will compress the memory occupied by applications that aren't being actively used and give the freed up RAM to the application that needs it the most.

  • AVG says using too much memory because multiple firefox's are open but I only see one.

    AVG scans regularly in background. Lately it has been showing a popup window that says multiple applications of Firefox are running and using too much memory so I should close some. But, I only can see 1. Tried CTRL ALT DEL to see if I could find answer, but only showed 1 firefox, and it was using over 28,000. So I think AVG is correct, but can't find out how to see what or where they are. They DO NOT show on the lower menu of the main screen, so I assume they are in the background. Don't have viruses, and Firefox regularly updates itself. What should I do to fix?

    Hi cmich80220-
    It's true you should only be able to run one instance of Firefox at a time. I searched but was unable to find anyone else with a similar issue. If the problem gets back to Firefox running slowly, you might check out this article for troubleshooting:

  • Firefox uses too much memory, gets bloated, and won't respond.

    For the past several versions of FF....I have posted here about it's 'behavior' under OS X.
    The browser uses too much memory. After a short period of time, it becomes 'bloated', slow to respond, and requiring a 'force quit' to get out of it.
    Being as I've posted about this before, for a previous version, and only received feedback from other Mac users experiencing the same thing, and not getting answers or help...I've stopped using it once more. It was a one day trial, and I didn't make it past 6 hours of use.
