Signal 11 Causing Tomcat crash
Really hoping that someone might be able to help us with this. We are experiencing Signal 11 crashes on our tomcat server. We have tried almost every configuration that I can think of and we are still getting these crashes at least once a week, sometimes twice a day. Unfortunately we can not reproduce this anywhere except production. Here is the current setup:
RedHat 7.3
Kernel: 2.4.18-3smp
Memory: 2.5GB
JDK: SDK 1.4.2
Tomcat 4.0.6
We are using mod_jk to talk to the Apache server (2.0.x) and the native DB2 jdbc driver to talk to our DB2 databases. We have also tried Tomcat 4.1.29 and Sun's JDK v. 1.4.1_01 and IBM's 1.4.1 on RH AS 2.1. We are passing the following settings to the JVM: -Xms512m -Xmx1024m.
We have also tried running this on three different boxes to try and isolate hardware failures, but all machines experience crashes in the same way.
Thanks in advance for any help.
Here is the beginning of the error:
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x59DF83B0

What architecture are you running on? I /think/ by default on Linux (and Windows) on Intel is 256k? (Someone please correct me.) If you don't have that many threads, try -Xss512k ; I don't know if this will help, but it possibly could help depending on what is happening at the native level. Did you have any luck using the 100% Java JDBC driver?

Tomcat crashes while running servlet chat in IE
Hi all!
I've seen similar problems posted about three years ago, but I didn't see an answer for it.
I'd be very grateful if you could help me.
I'm writing a chat, the code was taken from the J.Hunter "Servlet programming book" O'reilly, "absurdly simple chat", and adjusted (I only need the Http version). It's an applet-servlet chat.
When executed in IE, Tomcat crashes after a few (usually 5) sent messages. When executed in a debugger (I use Forte, the last available version, 4 update 1) the program works just fine...
Another question is about debugging an applet, executed in a browser - how do I do this?
Here is the code for the servlet:
=================================
import java.io.*;
import java.net.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class TryChatServlet extends HttpServlet
// source acts as the distributor of new messages
MessageSource source = new MessageSource();
// doGet() returns the next message. It blocks until there is one.
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType("text/plain");
PrintWriter out = res.getWriter();
// Return the next message (blocking)
out.println(getNextMessage());
// doPost() accepts a new message and broadcasts it to all
// the currently listening HTTP and socket clients.
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
// Accept the new message as the "message" parameter
String message = req.getParameter("message");
// Broadcast it to all listening clients
if (message != null) broadcastMessage(message);
// Set the status code to indicate there will be no response
res.setStatus(res.SC_NO_CONTENT);
// getNextMessage() returns the next new message.
// It blocks until there is one.
public String getNextMessage() {
// Create a message sink to wait for a new message from the
// message source.
return new MessageSink().getNextMessage(source);
// broadcastMessage() informs all currently listening clients that there
// is a new message. Causes all calls to getNextMessage() to unblock.
public void broadcastMessage(String message) {
// Send the message to all the HTTP-connected clients by giving the
// message to the message source
source.sendMessage(message);
// MessageSource acts as the source for new messages.
// Clients interested in receiving new messages can
// observe this object.
class MessageSource extends Observable {
public void sendMessage(String message) {
setChanged();
notifyObservers(message);
// MessageSink acts as the receiver of new messages.
// It listens to the source.
class MessageSink implements Observer {
String message = null; // set by update() and read by getNextMessage()
// Called by the message source when it gets a new message
synchronized public void update(Observable o, Object arg) {
// Get the new message
message = (String)arg;
// Wake up our waiting thread
notify();
// Gets the next message sent out from the message source
synchronized public String getNextMessage(MessageSource source) {
// Tell source we want to be told about new messages
source.addObserver(this);
// Wait until our update() method receives a message
while (message == null) {
try { wait(); } catch (Exception ignored) { }
// Tell source to stop telling us about new messages
source.deleteObserver(this);
// Now return the message we received
// But first set the message instance variable to null
// so update() and getNextMessage() can be called again.
String messageCopy = message;
message = null;
return messageCopy;

Those files are the only files needed to execute the program.The whole Tomcat crashes, and no exception
displayed.
Do I have to write the log file, or it's kept by
Tomcat itself?yes, tomcat writes a log file, you find it in the tomcat dir. but it's just very highlevel. Having a look in it could help.
Is there a way to write a log file by myself?sure. you could get the log file from tomcat by getting it from the ServletContext:
ServletContext = getServletContext();
ServletContext.log("text to log");
When I view the output window in Forte, it doesn't
even write that Tomcat crashed.
I use Tomcat that is installed with the last version
of Forte(Sun 1 Studio, update 1), I guess it's the
last version of Tomcat also.No. The lastest is 4.1.12 and i guess it's 4.0.4 with forte.
Get Tomcat standalone from jakarta.apache.org and try to run your servlet with the standalone tomcat. this could help since i also expirenced problems sometimes with the forte-integrated tomcat. -
I have files that are freezing my programs (adobe; after effect and photoshop, as well as maxon cinema 4d). Whenever I try to import ANY file from within the program it doen't even let me select the file I need before freezing. I have moved all files off my desktop and into my dropbox, and it now allows me to import files/search for files on the desktop but NOT dropbox, once I go to dropbox it freezes again. I am assuming there are files within dropbox now that are crashing my programs. The problem is I have a lot of files in there and would like to remove the corrupt ones so that I can use my programs without freezing. Is there a way to find the exact files causing the crash?
This has happened a couple of times and each time I have to move all my files off my desktop, so there must be a type of file doing this, I just don't know what files they are.

ANY help would be greatly appreciated! It is making it really hard to get work done. THANKS!This error sounds to me like you have/had BootCamp Windows installed and then removed, posible ?
If so (and even if not so), try restating your MBA while holding down the alt/option-key until you get to the Boot Selection Screen.
Choose to boot OSX.
Once in OSX go to System Preferences then Startup Volume and set your OSX to be the default.
Hope it helps

Using Disk Warrior on external drive causes MacBook crash
I work on MacBook System 10.6.7, I back up to LaCie external drive, which I partitioned so that one partition is only for backup, the other is bootable. On this partition I have a clone of Disk Warrior (4.1), to use on the MacBook .
Today I ran DW from the MacBook on the external drive for the first time, because lately it happens that the backup partition does not always appear in the finder (still performs back up though). I applied it first to the boot-partition, and it told me there were some problems. When it got to replacing the directory, the computer crashed mid way.
I performed Disk Verify on that partition through Disk Utility, and it said that it needed repair, and then that it did repair it. Checked other partition, no problem.
Tried again to rebuild directory for the external drive, and both partitions caused the MacBook to crash. I then booted from the external drive to see if it works, and ran DW on the MacBook, and had no problem there.
Anybody can tell me if it is the MacBook that caused the crash, or if the problem is with the external, and if there is anything else I can try to sort it out?

Use of discrete graphics causes hard crash - (MacBook Pro 2010 with ML 10.8.2/3)
I have a client with a Mid-2010 MacBook Pro. He was having crashes with Lion so I upgraded him to Mountain Lion 10.8.2. The crashes did not go away.
I troubleshooted and with the help of gfxCardStatus noticed that every time his machine went to use the discrete graphcis he got the gray hard crash screen and system had to restart. Back then I tried a beta of 10.8.3 and it didn't help.
I noticed that if I created another user account (profile) it would not crash when the discrete graphics card was called upon.
So, I re-installed the OS (to 10.8.2), created a new profile and manually migrated pictures, documents, keychain, mail, movies, music and re-installed the relevant Applications. Everything was working fine and my client went on a trip to Europe and soon the crashes began again. Then he upgraded to 10.8.3 and the crashes got even more frequent (it seems 10.8.3 puts more applications on the discrete graphics list so it switches even more).
I am wondering what could have caused the crashes to begin. It was before he upgraded to 10.8.3. Some application or something he was using must have changed a setting or corrupted something to cause the crashing to begin. I haven't done this yet, but I'm sure if I create another user account it won't crash on it.
Any ideas where to turn my attention to see what is causing the shift from his working user account to a crash-causing one?
He has iLife, Office 2011, Final Cut Pro X, iPhoto Library Manager, VLC, Audacity, DropBox, FileMaker Pro 11, Flip4Mac Player, Fuze, GotoAssist, Handbrake, Skype, iSkySoft DVD Creator, iSkySoft Video Convertor, Onyx and Skype.
I know there are *MANY* others having problems with the automatic graphics card switching and it seems some are having more problems when gfxCardStatus is installed?

Take a copy of the article with you when you go for service. They need to run a SPECIAL diagnostic to decide whether you have this problem. Do not leave until they run the special diagnostic. The "overnight run" does not detect this problem.
If they confirm you have the problem, they will replace the graphics chip, which is part of the motherboard. be prepared to hand over your Mac for depot repair. (Your backups must be up-to-date). -
Is there a way to track down the cause of crashes in SAFARI?
Not long ago I was able to eliminate one type of crash I had been having in SAFARI by following a suggestion made in this forum. Those crashes, however, were of the type that generated a 'crash report.' So they left a kind of 'paper trail' as to what was causing them.
More recently I have been having frequent crashes that don't result in such reports. These crashes occur apparently randomly when I mouseclick on a link. The spinning beach ball appears on-screen and never leaves.
Is there a way to find out exactly what is causing these crashes?
Thanks.Hello Michael:
I have not yet seen a
good approach to using that information (short of
deleting the account).
better search some yourself Barry <G>
if something runs fine in another account - one can isolate the cause to one of the plist files in the main acct Home/Library/Preferences/ or possibly an add-on in Home/Library/Internet Pug-Ins or ...Input Managers for example.
If there is the same problem in the new acct - you can discount anything with the main acct user library - plists,caches,plugins,input managers, the whole lot.
A useful tool is Console - found in Applications/Utilities/ keep it running while the 'problem' in question crops up & see if any messages pop up in either the system log or console log. Sometimes these will point straight at the problem area, other times no help at all. -
Sticky Notes in a pdf file cause ie7 crashed.
This is a very interesting bug.
System version: Windows XP with SP3
Adobe Reader Version: 9
IE version: IE 7
Files needed for testing:
a pdf file (note.pdf) with Sticky Note displayed.
a html file (note.html) which has a url link to note.pdf
Action which causes the crash:
1. Open note.html in a new IE window
2. Click the link to open the note.pdf in a new window or a new tab, then close it
3. Click AGAIN the link to open the note.pdf in a new window or a new tab, then close it
Then you could see the error window popup, the ie7 browser crashed. This has been tested in 3 PCs.
Check the Error Event, it said:

Hello everyone,
I am facing a serious problem. This is as follows:
1. I have wrote some audio/video conversion fuctions using C and make the shared library (*.so files) in linux.
2. I have wrote the JNI code (making it shared library also, *.so file) to access the library functions created in step 1.
3. Then I use JAVA and Java Native codes to use the JNI. I load the library created by JNI code with Java.
4. Finally, I have created a JSP page. Actuall JSP page acts as the conversion client program of audio/video conversion.
The problem is:
If I open the JSP page in one browser , the conversion is successfull.
But when I open two browsers and try to convert at the same time, the tomcat crashes, so conversion fails.
Why tomcat crashes ? Is it for JNI ? Is there any JNI drawbacks for such case ?
It will be greate help, if someone can answer.
Thanks in advanced.

hopefully i have the right forum for this question.
the IE cumulative update for the past few months has been causing IE to crash on one of our internal websites.
the March update (3032359) has a documented issue with table-based websites (which our internal site is); this issue isn't documented for the April update (3038314), however it's still crashing IE on this website.
if i understand the cumulative updates correctly, they're a roll up of individual IE updates. from what i can see, there's no way to uninstall these updates one by one.
my current theory is there's an offending update within the cumulative that's causing the crashing issue, but not sure how to isolate the offending update.
make sense? any help is appreciated.
thanks!Hi Matt,
>>if i understand the cumulative updates correctly, they're a roll up of individual IE updates. from what i can see, there's no way to uninstall these updates one by one.

thanks for the response; is there a way to uninstall individual updates that are included in the cumulative?
it's likely that one of these updates is causing our issue, and until we determine the offending update, we'll likely continue to encounter this issue going forward with the cumulative updates.
i can contact Microsoft support, but if there's a way for me to uninstall each update manually, i can easily take the time to troubleshoot this on my own.
any ideas?

Signal Booster Causing Problems
Can someone out there explain how the following can happen. After initially receiving FIOS for HDTV, I was experiencing no audio,video or functionality problems. Suddenly I was unable to connect to the server for PPV or use the select function to browse. "Server not available" was the screen message. A FIOS tech assessed that weak signal was causing the router to not stay current with the guide and also prevented server connectivity. He replaced the router and installed a Motorola signal booster which not only solved the problem but increased my internet speed and picture quality . However, after he left I discovered HD channels 900 and up and 750 were not viewable. "Not Available" was the screen message. How can the signal booster selectively prevent receiving certain channels. A FIOS tech is coming back today as all efforts by the office to re-boot and send authorization codes and tests failed. HELP!!!!

Solved!
Go to Solution.A happy ending. Two FIOS techs arrived and replaced a 15 foot run of cable from a splitter that I had installed (signal loss), and reduced signal strenghth to the router as it was too hot with the PDI MOCA power booster. Somehow this combination solved both the failure to be able to connect to the server, and reinststed channels over 900. Go fugure. The logic of needing both a booster and a reducer does not compute.

OVM 3 Generic Storage Plugin. Acess Group configuration causes server crash
Our iSCSI management is currently entirely done manually at the servers console, because we still don't have a SAN Equallogic storage plugin.
At OVM Manager interface, what we thought being just useless in our case (SAN Access Group), is the actual iSCSI connection (and disconnection..) management for servers.
Following the upgrade to 3.2.1, setting up the SAN did nothing more than what we do manually. But undoing part of it caused the crash.
All over OVM Manager, any operation/setup that could impact running VMs is denied... Except there, at the real root of everything.
Removing a iSCSI initiator from that panel disconnects abruptly the iSCSI disk, !!!! without warning !!!!.
Then, after the 60s timetout, the physical server reboots.
It is still not clear if we get a benefice to setup that "Access Group" of the SAN or not. At least, once setup, we know that we'd better keep it...Updating OVM 3 host to use "brbond0" vs "xend" managed bridge to allow direct hosting of OVM Manager VM.
Update "ifcfg-bond0",
[root@ovm322 ~]# cat /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
BONDING_OPTS="mode=1 miimon=250 use_carrier=1 updelay=500 downdelay=500 primary=eth0"
ONBOOT=yes
BRIDGE=brbond0
Create "ifcfg-brbond0",
[root@ovm322 ~]# cat /etc/sysconfig/network-scripts/ifcfg-brbond0
DEVICE=brbond0
BOOTPROTO=bridge
ONBOOT=yes
IPADDR=A.B.C.D # IP address of ovm322
NETMASK=255.255.254.0
NETWORK=A.B.C.0
GATEWAY=A.B.C.1
Update "/etc/xen/xend-config.sxp",
# Enable network-bridge, JAP 20120618
# Disable network-bridge, JAP 20131223

Update "vif" for OVM Manager 3 "vm.cfg",

Emptying iPhoto trash causes iP crash
and it rhymes!
Using latest version of iPhoto, I was deleting a number of photos a week ago or so when iPhoto crashed. When I re-opened iP after a restart, everything seemed okay, so I proceeded to add more photos to the trash folder and tried again. It crashed again. It's obviously doing something because all of the thumbnails for the photos in the trash are gone (nice little box with dotted line) and if I try to view a full size image, it gives me a big box with a small question mark in the middle.
The left info window shows the file size, date, etc of each photo still so it seems to me that the photo is still there, but not displaying, not to mention that I can't delete the 1 GB or so of images I have in there. I've tried doing everything in the ctrl-option window but to no avail.
Is there any way I can get rid of these photos? Thanks!I can't figure out how to delete, so this has been solved. It was just one file from another persons camera that was causing the crashes. Removed that, deleted all the rest and then deleted the one photo by itself. MAGIC!

Vodaphone dongle causes panic crash. Help please?
It is essential for me to use a Vodaphone dongle for certain work purposes. After installing Snow Leopard, dongle caused panic crash in my MacBook Pro. 4 panic crashes and reports to Apple later ... alert message appears as follows.
" System/Library/Extensions/USBExpressCard can't wake_Huawei.kext"
Check out support and hit on Welcome Wake Up issues. More like Unwelcome! Is this the problem?
Have reinstalled Leopard since this dongle is the only way to connect at work.
Any ideas?Hi everyone
Vodafone really have not excelled here but today tracked down a solution using the GlobeTrotter application to intall the right modem driver (not sure but I think this was the problem causing kernel panics)
Here is how to do it...
1. Make sure you delete any extension from the System/Library/Extensions folder containing the word "Huawei" in the file name
2. Restart
3. Download latest version of Vodafone Mobile Connect (which by itself will still cause kernel panic if you install and then plug dongle in and install.
4. Download latest version of GlobeTrotter Connect (http://support.option.com/att/index.php?title=GT%20Connect%20for%20Mac%2010.4.11 ,%2010.5.x%20and%2010.6.x%20and%20Manual&action=module20/index)
and install it.
If asked to confirm new network preferences do so - this I think installs the updated modem driver which I think was the source of the kernel panic previously.
5. Then insert USB modem - should not cause kernel panic!
6. Then run the Vodafone Mobile Connect software and press Activate
It works and does not crash!!
Good luck! -
