That's the error I get. When trying to run a java app with the firefox plugin, the browser simply crashes if it's the 64bit java or tells me it's not installed if it's the 32bit version.
I'm at a loss as to what to do. I think it has something to do with leftover gunk from a previous version I misinstalled(Is that even a word?) Anyway, the only thing that google could come up with was a solution for windows which laid blame on Bill Gates for having a bunch of pf (java prefetch) files stuffed into c:windows for no apparent reason. The solution was to delete them, but I can't seem to find the java prefetch folder in linux. The method I used is downloading the rpm from java.com the rpm2tgz then installpkg then cp libnpjp2.so to firefox plugins folder.
I am still confused about the memory issues. i have allocated JAVA_OPTS='-Djava.awt.headless=true -Xms512M -Xmx512M -XX:MaxPermSize=512M' think that it means that i have allocate java to use only 512mb of my memory. but when i run top here is my output.

View 13 Replies View RelatedHas anyone seen this error in libvirtd?libvir: QEMU error : out of memoryWhatever it is, I'm pretty sure that's what's keeping my virt-manager from working. There's 12GB of DDR3 on this box, so I really really hope that it's not actually a memory problem. This here is a brand-new whitebox I build just for virtualization on F11. Can anyone here help me make it work?
Edit: This is a 64-bit install. All 12GB are accessible by the OS.
I have a java program that runs on Debian as a background processor. Yesterday the Java program stopped running. I looked at the memory usage, the system only had 5MB memory left, so my guess is that the java program ran out of memory to use.
However, after we restarted the java program, we could see that the free memory count started to go up. It kept going up from 5MB to over 400MB. The increase of memory happened slowly, when I measured it, I could see that with each minute passing by, there were a bit more memory added into the free memory pool, and meanwhile, the java background process was running.
I wonder why this would ever happen. It's as if our java program first brought the machine done because it consumed all the memories, then after restart, it starts to give back memories.
I am having a problem with lockups on a new FC12 box (dual core 3 ghz, 4 gb memory,HDPVR,nvidia 8400gs). This happens reliably when replaying MythTV videos, but also randomly at other times using other apps (I suspect also boot but I can't be sure; it just occasionally stalls part way through the boot display).
Usually but not always this is accompanied by a kernel panic (caps lock + scroll lock lights flash on keyboard).
I did a core dump with kdump and it reports:
Thread 1 (<main task>):
Cannot access memory at address 0xffff880028025b70
I am in the process of running memtest86+ right now, and it's been through several passes without errors. I know it needs to run more, but given the reliability of this problem with MythTV video playback I am wondering if the problem could be in the video card memory.
Does anyone know of a linux (or bootable) tester for video memory? All I am able to find are some things for windoze like this.
Also is there any way to track that address from the core dump back to a physical location?
To get the kernel messages of new java process, i refer the details from /proc/<java pid>/stat and /proc/<java pid>/statm files. For some java processes, I didn't find any details in the /proc/<java pid>/statm file. It has only 7 number of 0s. But /proc/<java pid>/stat file has the details. And also this kind of process will have the life time of nearly 1 minute.
Kernel version using: Linux-2.6.18-8.1.8.el5 Is there any possibility of java process without the memory details in the /proc/<java pid>/statm file? If it is possible, how to know the memory related details of that processes?
I am using Fedora 7 for making a server. I have installed Kaspersky mail gateway solution on that. but the solution is not working.

View 3 Replies View RelatedI have run into an issue with Fedora on my laptop that has me stumped. On this laptop I had partitioned the hard drive with Windows 7 (came with the PC), and initially Fedora 13. This setup worked fine for about four-five months, but recently Fedora will no longer boot. One day I attempted to load the OS and after GRUB get a screen that says "Error 28: Selected item cannot fit into memory." Windows continues to load fine however, and a memtest worked fine as well. When I attempted to run my Fedora 13 live-cd, I got the similar error "Error 28: Not enough memory to load this specified image."
Now, not having anything critical on the Unix partition, I decided to delete the Fedora partitions and start from scratch. I did so and the computer successfully loads a Fedora 14 live-cd albeit slowly (but still not the 13 one... I'm guessing the CD is just corrupted from scratches). Unfortunately, once I installed Fedora 14 on the empty space and tried running, I get my original error dealing with the item not fitting into memory. I'm out of ideas, and getting tired of the machine being Windows only.
The specs are as follows:
ASUS UL80VT Notebook
Intel U7300 1.3Ghz
4GB Ram
GRUB reports memory as:
607K lower / 14272 upper
I was coding some java. I had just finished setting everything up & everything was working fine so I kind of freaked out when I typed `javac hw.java`, and I received a weird error. I can't remember it exactly but from that point, I was not able to use any java-related command anymore. `javac`, `jar`, `java`.... I kept getting the same error. Something like "java runtine environement error", but it may not be that exactly. It kept creating .log files in my /home/maden/ folder, but as my topic title says, I can't reach the boot screen anymore ! I have no idea if the two problems are related but I think they are. When I got home, I restarted my ASUS eeepc 1005h and reached the KDE login screen anymore! I turn on my computer, it goes to the GRUB loader, I select fedora core 11... I then see the fedora fedora logo slowling filling up, as usual, and when the login screen is supposed to pop up, it does not. It just remains black. So now, I can't do ANYTHING, can't even login as failsafe or nothing, my data seems unreachable!
