Solaris Heap grow for no reason ....
Hi all,
This is a tricky one. I have played around with Java under Unix for a while. My programm was working under Sun Ray with a normal heap with version JDK1.4beta3. I then decided to put it under JDK1.4rc.....
Boum. The programm keep on exploding after 6 to 7 hours of threading with giant size core dump ( heap size ) obviously above -mx...m
I track down the heap with pmap -x PID | grep heap ... It keeps on growing for no reason and it wasn t doing it with 1.4rc .....
Strange enough the difference between System.TotalMemory-System.freeMemory is fluctuating has if the heap section of pmap has got nothing to do with this.
Any obvious thought about it ? the command is the same and the compilation is on the jdk I am running under.
Yeap,
- All patches are in the box...
- JDK1.4 last release does the same to me
I misspelled my last mail... My problem is not on JDK1.4beta3 mixed mode which works just fine. It happens when I moved to JDK1.4 and last release ( downloaded last week).
The problem is on Solaris 8 accessed through a remote X. I already know it is very slow for repainting and it is not advisable to do that, but as it was working better and better from the 1.2 onwards....You know you give it a try.
My last thought is upon the overhead of some threaded action? Possible?
Do you know what part changed from beta3 to release candidate in the JVM?

New Multi-OS/CPU aware virus broke through virtualbox. For a reason.FYI
FYI (all)
Dear sir (RMS @ GNU),
my apologies. That e-mail concerned the embedding (secretly) of personal information during the make process of certain gnu software but there's a new developent and I'm extremely mad : I have been looking for ways to de-obscurify certain (gnu) Make processes. During my search I found a certain GITHUB repo that provided a way to do that. It was not "AO" but another... In reality it was a virus and/or a magic trigger that broke and destroyed All my systems in a manner of 2 hours or so.
It's a special case, methods used are not mentioned anywhere on internet. This one is multi-os aware and broke through a running virtualbox installation (I suppose via I/O hooks exploits yet unknown ). Both host and guest gets destroyed, independant of OS!
from what I have seen:
- the maker has somehow trojaned the Freedesktop.org desktop-daemon- input dbus helper software to gain and maintain root via init. Virtually everydebian based is thereby vulrenable.
- the maker has found a new way (unknown to every antivirus software) to gain Admin acces to windows system via lowlevel IO and/or abused "signed drivers" - and mmaps itselfs there to propagate..
- the virus broke through running virtualbox installations (latest installation, new installations, old VDI's) and they got all destroyed, first guest and hours or days later both host and guest installations.... also new.
- the virus injects itself on every network IF / download / and propagates on installation (triggered) within the virtualbox installation. This happens on the host too, but hours later.
- it eventually kills every document on every OS by spawning hundreds of processes to kill documents (overwrite, move, symlink)
The strange thing about this, is that GNU sources / software like the sourcecode for GLIBC and GCC was left alone! Because of that and the mentioning of GNU on that repo I contacted GNU. On my windows system there was even a special message "Thanks to Freedesktop and embedded Ruby".
The virus was obviously not meant for worldwide propagation but to target a certain audience (I suppose people like me), it's been engineered beyond belief and I triggered it somehow. In order to clean my system I tried a ISO/USB boot from AVG (linux based.) I booted from that USB and it got infected upon scanning... amazing.!!
Anyhow.. sorry to have bothered you.
Regards,
To microsoft: Windows : is trojaned via virtualbox Usb I/O and/or other lowlevel I/O trickery. Obviously new methods are used, hard to reproduce and I can only mention a few details : virtualbox breakage like this is not yet mentioned anywhere and no admin priviledges are needed to reproduce. this "virus" has no signature known to clamav/kaspersky/mssc/avg/macafee. New exploits are obviously used, unknown and/or used in a similar manner. Microsoft should investigate this on their own.
To FreeDesktop DBUS daemon: has been abused (and this darn thing is used in many debian based INIT scripts etc, in order to gain and maintain root (or worse). There was a note left on my system "thanks to freedesktop and embedded...": every Linux instance, new or old (2.6 to 3.2xxx was infected immediately). FreeDesktop: I *** your** because similar trickery is mentioned since 2009.
To certain people at Debian: thanks for not taking me seriously or even understand what you are doing. Clueless.
To Oracle: Every HOST that mounts an infected VDI, gets infected immediately upon boot. Or the other way around: upon scanning the filesystem. The scanning OS itself gets trojaned (reproduced via multiple USB installations/Gpart ISO, AVG iso) and gets destroyed . Even within virtualbox ..... the ISO grows to hunderds of gigs. Virtually. I suppose it's hooked via USB transport to gain accces over keyboard and mouse. In fact it doent matter what OS is used, the killing process is "universal" because it happens within the hooked kernelspace.
To reproduce : I cannot give much details and its hard to traceback or reconstuct the order of events but I wanted to look for a way to de-obscurify a certain gnu-make process (in particular a piece of GNU software (for ..keys) from which I suspected to embed privacy information about the user and this software is used on virtually every OS and in many software packages as building block. And I certainly found one. I guess some magic 0xUL that passed my system or action I did -triggered this OS independant chainreaction or "OSkiller" process. I should have suspected this.. well. Even github trickery was (AB)used ~/.git / gitprocesses are used for some reason because every new download got the "make" process treatment instantly. Tricks to use parts of sha1 signatures (actually the gitters identification. Some people are aware of these methods and are abusing this system, not to "watermark" but to pull off this kind of work?
The result: all my virtual Linux / Freebsd VDI/VMDK installations were completely destroyed within a manner of minutes and later the host (windows7, regular update cycle, well maintained and secured) too. It was hard to traceback and/or/try forensics because the host got infected too -- obviously no way to sandbox. (maybe I'm not clever enough). Mounting from another OS is killing that OS too. Amazing. The reason I wanted to traceback or mount a certain partition was because it contained my work on my research. I had backups (even incremental) of some instances and they all got destroyed too (unaware of the systemhooks that were luring for the magic).
Reproducable? Yes. But hard to pull off and therefore I suppose this "virus" is not meant to propagate worldwide but targetted at a certain audience. The maker(s) has/have deep profound knowledge of windows internals, virtualbox exploits,, linux exploits, methods not seen by any anti-vir software I got running. It means there's a whole bunch of multi-os exploits, application exploits, not used or mentioned anywhere, bundled in a well prepared trap for anyone who gets the magic. I still have the infected VDI's. cannot tell if they are completely destroyed because I dare not mount it in ANY way. (I tried virtually every way possible!!!!!). Forensics could do some work on the raw material.
Here's a brief list of software that must have already been trojaned / to kill the running OS's (on host/guest) of a target:
- "nonfree" linux-firmware. Certain IO/dev (dbus?) userspace layers (linux)
- linux or windows virtualbox guest addition(s): CERTAIN debian updates (* triggers the killing process). Especially the RE-make of IO kernelmods process caused a chainreaction in one case. The maker(s) did some magic there because one should assume that KERNEL code is well maintained (like Theo.d.r. does :-) )
- (gnu) remake processes of kernel mods (RT/Pre-emt) -> guest additions. I could only reproduce this a few times because my host got killed.
- github trickery....
- techniques: callbacks via IO hooks on both HID and available network devices and injects itself via sockets (because every download was infected)
- I suppose no known shellcode was used or not recognised. Every virusscanner that I got running got killed and infected upon scan, both windows and linux based, clamav and AVG mssc, macafee, kaspersky etc etc. Even a simple mount gets a host killed. Amazing.
and all of this must have been "packaged" for a special occasion? Its profoundly layered, multi-disciplined and networked (I guess there are more related triggers to this network) and this OS killer must have been ready or "waiting" for months, none of the exploits I've witnessed are mentioned on internet or have been used on seperate occasions (except for the dbus trickery: there have been rumors but no real actions by ubuntu or debian etc etc). All these multi-cpu/os/software exploits (means transports) events that happened on my systems, both metal and virtual, are not mentioned anywhere or seperately used on other occasions or else someone would have mentioned it? Even the slightest kernel breakage or trojaned kernel in this respect should gained prestige for certain w/b hat hackers. This is beyond belief. The guest/host breakage is amazing, multi-os and the killer does its work profoundly.
- so oracle can deal with this virtualbox breakage from host to guest and vice versa
- linus gets his multi-OS io / kernelspace breakage, kills of every mount or gets triggered by even mmapping.
- microsoft no idea.... no blame this should have been recognised within the security framework, but there's obviously not yet a signature known.
I don't know if I should call this a virus. It uses virus-like techniques but on so many levels happening at once. I dont think oracle or microsoft or linux / freebsd /solaris is targetted. It looks like a well contained (only propagating on the host/guest, even socks are targetted only at localhost) - trap, the killing process is very persistant and for a reason. If this was used in a network-propagating carrier virus it should raise a Major worldwide alert. I think this unknown network of suddenly revealed exploits are means to immediatly shutdown/completely kill the running system(s) of a certain audience (like me). It's like a network and eventually a killswitch, a "destroyer" which I happened to trigger while I was investigating some things concerning privacy issues (in fact building blocks for signing of public keys). This message should raise some questions.
And about that github repo. It's not AO.
Thats all folks.
0XWe would really like to debug your problem but the provided information is not sufficient and very hard to parse. A few questions:
- Which version of VirtualBox are you using?
- What host systems did you use to test, only Windows 7 or also other systems?
- Did you try to use an infected .vdi disk with a fresh installation of VirtualBox on a fresh host?
- Which guest is affected (exact version please)?
- You report that even your host will be infected (breaking through from a VirtualBox guest to a host). Did you do scan your host for viruses before you started your guest so you can be 100% sure that your host was clean before it was infected by the guest?
- When scanning the infected system with a Linux-based virus scanner: Did the scan report any problems? If so, which? And did you consider to use a virus scanner on a read-only boot medium? In the latter case it is impossible that the virus scanner gets infected.
I would appreciate if you could answer these questions, there could be more questions once I have the answers to these. But please, try to be precise and short when answering the questions. -
JMS Messages keep on growing for a Topic with non-durable consumers
I have a JMS Server whose "Messages Current" keeps on growing after every message send to the topic. All the consumers are non-durable. The session is a non-transacted session with Auto Accknowledge parameter. My client does recieve the message, but it does not go down from the "Messages Current" in the WLS console. Also once the server is restarted, the messages go down to 0.
I am using 9.2 SP2 on a Solaris environment.
Any insight would be helpfulIt's possible that one or more the subscribers is stalled for some reason and so is not actually receiving and processing messages. This would cause messages to accumulate. You can examine statistics for individual consumers on the console to see if this is an issue.
Also, there could be a durable subscription on the topic left over from some previous application you used with the topic. There are statistics for these as well.
Yet another possibility is that the clients are receiving the messages but are failing to acknowledge/commit them. You wrote that the sessions are "auto-acknowledge" but they could accidentally be "transacted". Check to make sure that the first parameter passed to "createSession" is true (it should be false), and that the second parameter is set to auto-acknowledge.
Finally, if you happen to be using a distributed topic, keep in mind that if one of the topic members is unavailable/crashed/down messages will accumulate on the other distributed topic members until the unavailable member is restarted (at which point they will be forwarded to the restarted member).

I only sign in to iTunes' store about once a week or so. But during each of my last 3 attempts (on different days, several days apart) on my first attempt to enter my password and hit submit, I am immediately told that my Apple account has been locked for security reasons and it wants to take me to a page to reset my 'forgotten' password. I am using the CORRECT password.
Perhaps someone else is trying to break into my account or is mis-entering theirs but my account should not be getting locked like this. It is very frustrating to have to go through the reset password procedure each and every time I want to go into the store. It seems to me that Apple really doesn't want me to buy any more apps from them as they keep refusing me entry into my own account, each and every time I have tried to use it, for the past few weeks. I am not their best customer, but they aren't giving me much of a welcome invitation to become one, if I'm going to be treated like this.
I just bought my iPhone 4 less than 2 months ago. I paid extra money to upgrade early, just to get this phone because it was so highly recommended by everyone I spoke with in different stores (BestBuy and Verizon). I even bought the 2 year upgrade to my Apple services in case I needed to ever call them, and so far I haven't had to, yet. But I definitely will call them if this isn't straightened out.
It looks like this other user could be tracked and an email could be sent to them from Apple to let them know what they are doing - trying to sign into the wrong account, and are locking somebody else out of their own account because of their error....and to remind them of their correct information or how to get it and to write it down or save it somewhere so they don't keep on doing this.
I have seen literally DOZENS of other people in these discussions with exactly the same issue that I'm having so it is NOT an isolated incident, and it seems to be a growing problem as Apple's sales and user base continues to grow, so this problem is seriously needing to be addressed in some way, and soon, before they start losing new customers because of it. If I was still within my original 14 day return period with this phone, I would definitely be returning it and buying an Android model because of how frustrating this is to me. If my bank was doing this to me, I'd have already switched banks by now if they hadn't fixed it - just to give an example of how I feel about this.For what it's worth, you posted this in 2011, and here in 2014 I am still having this same issue. Over the last two days, I have had to unlock my apple account 8 times. I didn't get any new devices. I haven't initiated a password reset. I didn't forget my password. I set up two factor authentication and have been able to do the unlocking with the key and using a code sent to one of my devices.
That all works.
It's this having to unlock my account every time I go to use any of my devices. And I have many: iMac, iPad, iPad2, iPad mini, iPhone 5s, iPod touch (daughter), and my old iPhone 4 being used as an ipod touch now. They are all synced, and all was working just fine.
I have initiated an incident with Apple (again) but I know they are just going to suggest I change my Apple ID. It's a simple one, and one that I am sure others think is theirs. I don't want to change it. I shouldn't have to. Apple should be able to tell me who is trying to use it, or at least from where.
Thanks for listening,

HTML output on NT and solaris are diffierent for a report
Hi,
I have created a report on win2000
and did the deployment on Solaris box.
When i call a report from a nt box HTML
looks fine but if i call same report from solaris box the font size is changed and also the formatting.
This also affects the PDF format.
Any help will be highly appreciated.
Shaileshhello,
when moving form NT to UNIX (or vice versa), you have to take in
account, that the fonts you were using on one plattform might
not be availble on the other one.
for that reason, reports provides you with font-substituion
functionality in form of the UIFONTS.ALI file, where you can
define substitution rules. if you have not set up this file, the
fonts will be substituted by a default font, which most likely
will not be the same metrics as your original font.
but be aware, that the metrics of fonts are different, so you
might want to check which font on plattform A is best
represented by which font on plattform B.

Iv downloaded the 0845 wizard from the App Store. Registered my details and it has been working. But for some reason it won't let me log in and keep saying failed every time I try to use it. Iv deleted and re-downloaded the app and it still says the same?
I would say to start by looking on their web site... unfortunately, that appears to be dead.
Based on the horrible ratings on the App Store (1 star for the current version), I'm not surprised it doesn't work well. -
I have downloaded all of the recent upgrades for both Itunes and Iphone. Now for some reason, not all of my songs in my playlists are transferring when I sync. Previously I have had the songs in the playlists on my phone, but now some of them are not there although they are listed and show in Itunes. Any ideas?
iTunes will only copy back iTunes purchased music. If you don't still have a copy of the music that you copied from CDs or bought from other stores anywhere (e.g. on another computer or on your backup of your library) then there are some third-party programs listed half-way this page which should be able to copy them back : Recover your iTunes library from your iPod or iOS device.

For some reason, I cannot change my desktop background no matter how many times I delete the "active" folder. It's as if it's locked. Any ideas how I can fix it?
Yes it sounds like you have a corrupted preference file.
The setting you make in individual programs get saved to a Preference file in your Users/Library/Preferences folder.
All you have to do is drag out the old file to the desktop, reboot and load the program and the preference file gets rebuilt without your preferences which you reset.
For your case I beleive the preference file is
com.apple.desktop.plist -
Downloading a file would normally bring up an option to open the file with the appropriate program or save it - for some reason now it just downloads straight to the download folder. Why? Problem with Firefox or something else? It's very frustrating - sometimes you want the file opened first so it can be discarded or saved to a different location.
Hey. that's great! Thanks for posting back with the outcome.

I have about 70 Cd's loaded on my computer as I had previously owned another MP3 device before I got enamored with the Ipad and Iphone. My problem is itunes will not recognize all of this music. To give a specific example, I have an old Bon Jovi Cd "crossroads" , itunes only recognizes 2 songs off the Cd. How can I get itunes to recognize these songs? They do not show up on itunes anywhere but if i go to my music folder I can locate the songs and it even shows the itunes logo but, the songs will not play with itunes. I've got a few hours of music i would like to have on my iphone. Can anyone please help me with this?
It has always been very basic to always maintain a backup copy of your computer for this very occasion.
Use your backup copy to put everything on the computer, then sync.
If for some reason you have failed to maintain a backup, not good, then you can transfer itunes purchases from your iphone to your computer - File>Devices>Transfer Purchases -

hey iphone an iphone 3g and i only have about 13 apps and the yellow bar on itunes for my phone is way to big i deleted all my photos all my music every thing i ryed restoring ans all it still takes up space for sum reason ?? please someone help me
If Other (the yellow bar) is too big something is corrupted. The only solution (that I know of) is to restore from your most recent backup using iTunes (see http://support.apple.com/kb/ht1766).

One of my apps (actually on my daughters i phone 5) has been "waiting for 4 days to update. Rebooting doesnt cure it nor does trying to delete it - it wont delete. I have looked at her i tunes account but she hasnt sync that for ages and the actual app isnt in i tunes but just on the phone. For some reason the syncing isnt working either in realtion to this app. There is adeqaute memory - good strong wifi signal. Any ideas??
Download the app on iTunes under her account (you've already paid - you won't have to again), then sync the app across to the phone that way and it should clear it up.
It's possible the app is too large to do over the air and it started on wifi but wasn't able to continue and got corrupted.
