Hi all
I am new on this forum but I use Wildfire Server since months, my current setup is this:
OS: Ubuntu 6.06 LTS
JAVA: Official from Sun 1.5
Wildfire Version: 3.0.1
Using a SQL Server 7 DB
Well, I do not why my post was cut in half, My wildfire server crashes sometimes (more or less 2 days) leaving a log file like this:
-
An unexpected error has been detected by HotSpot Virtual Machine:
-
SIGSEGV (0xb) at pc=0xb76f9df6, pid=26314, tid=2843216816
-
Java VM: Java HotSpot™ Server VM (1.5.0_07-b03 mixed mode)
-
Problematic frame:
Sorry me but I do now know why I can’'t post any more than 8 lines of text, everything down is cutted down.
I will not post the whole file if you guys need any specific part please tell me.
The server is also running other services
Thanks !

Hey Andrew,
That is a Java Virtual Machine error. Try updating to latest JVM version (1.5.0_09) and also make sure that you are using latest OS patches.

Hi ! thanks for your answer…
I did what you told me (updated to 1.5.0_09) and it lasted one day, I got a crash again…
What else can I do ?
Thanks…
What about applying latest patches to the OS? Are you using any other plugin that uses some native libraries?
Regards,

Hi, The OS is updated, I tried with:
1.5.0_07 , 1.5.0_06 and 1.5.0_09 with the same problem, in the crash log says “problematic module libjvm.so” maybe that says something?
The command executed is: root 25927 27.9 14.0 279216 54280 pts/0 Sl 09:59 0:25 /opt/SUNWappserver/jdk/jre/bin/java -server -Dinstall4j.jvmDir=*/usr/java/jre1.5.0_07 *-Dinstall4j.appDir=/usr/share/wildfire
I switched to SUNWappserver version as you see, but jre 1.5.0_07 still is used as jvmDir, why is that?
Hi,
there are only little bug fixes within these minor releases. But making sure that the latest version also has the problem is usually required if one wants to open a bug report at sun.com.
Could you please post the lines below “Instructions” and the lines below “Java frames”?

I updated Wildfire server to the latest and still the same…
Instructions: (pc=0xb76424c6)
0xb76424b6: c3 bc 44 3e 00 8b 16 85 d2 74 35 3b 57 1c 73 30

I Do not have “java frames” I do have “native frames” :

This happened some time ago for me on a solaris machine. The problem was due to JVM version v’'s OS patch level. As suggested above this is where I would look.
Cheers,
Conor.
Hey, could you please specify wich software was involved in patching procedure? maybe works for me as a clue…
hi. just a note to say my wildfire server has suddenly started crashing in exactly the same way.
os - fc6 (kernel-2.6.18-1.2798)
jvm - version that comes with wildfire (1.5.0_08-b03)
wildfire - 3.1.1-1
database - mysql 5.0.27-1
let me know if you want any details from the hs_err log.
Hi Carrot,
I’'d like to know if you did update something (kernel, libs, …) before your server did start to crash.

it has only started happening in the last couple of days. during that time the following packages have been updated :
Dec 10 11:15:22 Updated: bind-libs.i386 31:9.3.3-0.1.rc3.fc6
Dec 10 11:15:24 Updated: bind.i386 31:9.3.3-0.1.rc3.fc6
Dec 10 11:15:24 Updated: caching-nameserver.i386 31:9.3.3-0.1.rc3.fc6
Dec 10 11:15:25 Updated: bind-utils.i386 31:9.3.3-0.1.rc3.fc6
i decided to use a good old strategy that i normally only use for windows operating systems, i uninstalled and reinstalled wildfire. fingers crossed it has been stable ever since.
Hi Carrot,
if it does happen again please open a new thread, and post the hs file there.
As you did update bind I wonder if you are using need IPv6. If you don’'t it you could add “-Djava.net.preferIPv4Stack=true” to the java start command.
