I need a little help here.
We have installed the Cisco Works on Windows server 2003 32 bit, and right after Cisco wirks are installed CPU and MEM usage grows very fast, and at the end when mem is full server freezes and it stops responding at all, tha it need a reboot.
Anyone who had the same or similar problem that with solution which can help me ??
you don't state how much RAM your server has and which version of CW you installed. CiscoWorks really does use the memory stated in it's release notes - if the server is short of RAM then starting CW can take a very long time .
thank you for reply. This server have 3.6 GhZ CPU and 3 GB RAM mem. Should be enough..... I think
well, the data sheet (I assume LAN Management Solution 2.6 or 3.0) says
Intel Pentium 4 at 2.6 GHz for 1 CPU with 2 GB RAM memory 4 GB swap space.
for the 300 Elements version.
You need to set up swap space twice the size of the physical memory
Oh, and try to disable any antivirus, at least during setup.
The bigger packs have higher requirements,
Hope this helps.
so there is nothing I need to configure in Cisco works, but just check the swap (paging file) ?? someone told me that java could also make a problems as CPU and mem grows ......
Thank you for explanation so I`ll try it soon. I am waiting for VPN login info so I can log on that server and check this.....
Please if there is something more I can do about this problem so just let me know.
of course there are a lot more things that can eat memory. Since CW (at least the 2.x versions) depends heavily on java, it is very memory consuming. I understood your question as being directly after installation of cw, so there's nothing configured yet and it can't have any trouble with managed devices.
I've noticed the behaviour when installing CW, where it does stop and start the services with each package (CD) it installs - with less memory than stated it takes nearly forever - 30 minutes instead of 45 seconds on a server where the customer told me "I'm going to upgrade from 2 to 4 Gig tomorrow".
If your system already was up and running and isn't any more, can you tell me what happened before, which CW version and how many managed devices?
Best regards, Hartwig
Hi again !!
I understand what You mean. I have not received any login info yet, but once I receive it I will log on to the server and check what you asked me about, and I`ll let You know what is installed excat and which version.
So You`ll know about it !!
I like to share problems-solutions with people so there is no problems at all !!
Thank You for helping again !!
but for know I only know that CPU and MEM usage grows right after the Cisco Works has been installed, which means nothing was configured at all........
So paging file or java could be a problem, but I`ll let You know !!
Hello again !!
Well now all I have seen on the server, the problem could be java.
In the process task manager I saw:
cwjava.exe opened 2 times and using :
cwjava.exe 91372 of mem
cwjava.exe 95336 of mem
java.exe 26208 of mem
java.exe 13800 of mem
java.exe 33780 of mem
java.exe 299772 of mem
So we don``t need more than one cwjava.exe file and one java.exe isn`t corect ??
Any suggestions ??
more than one instance is perfectly OK. CiscoWorks has many processes running concurrently, and at least the different servers (RME, Campus Manager, Fault Manager..) use their own instance. I'll have a look at a customer's CW server when I'm there tomorrow, to see whether your memory totals are OK. But anyway, the given numbers add to less than one gig, so they shouldn't stall a 3gig server.
my productive CiscoWorks LMS 2.6.1 (75 managed devices) currently has
1x java.exe with 59288k
2x javaw.exe with 3700k and 8144k
34x cwjava.exe with mem from 228k up to 145976k
PerfMon reports a page file size of 3.21GB
and a Peak Commit Charge of 3549200 K
So I think the values you posted are perfectly ok.
By the way, are you sure your server OS exactly matches the specs with regards to service packs, language and locale (do NOT use anything other than US english!)
Sure the server matches all specs, all service packs are installed....
And I use only US English !
very wired problem
