What could this mean? It keeps appearing on my console. I"m trying to install a Fitbit Tracker and can't get it to recognize the device. wondering if this has something to do with it. Thanks!
It means you've installed some kind of third-party VPN software that isn't working.

When I try to do the iOS7 update, it keeps giving me an error message saying "an error has occured in dowloading." What could this mean? It doesn't tell me anything specific as the error...?
Got the same thing. Was in the middle of the download (11 mins remaining) and a blasted text message came through. Answered it, like a moron, and when I went back to download it gave me the error.. Very annoying. Anyway, perseverence paid off as after 10th or something re-attempt, it began again. (32 mins remaining). Like the guy above says. Severs will be going mental at the moment so stick with it.

But this problem is understandable, as the database is not running. The main problem why database is not running, I have found the reason but do not understand how to solve the problem.
Since, the database was not running, I tried to startup the database, I then came across the following which is my problem (Why so many files are open? Linux OS error says too many files open. See below,

Can anybody has run into such problem and guide me to a solution, please?
ThanksHi,
yes, this DB was functioning o.k. this configuration script was part of RMAN daily backup.
Last night the backup failed. So, when I opened "Failed job" in the EM, I saw this type of messages.
That was the starting point. Gradually, I tried to narrow down on to the actual problem and found the findings as I have posted.
One way of sovling problem, I thought that, all these processes I would kill and then try to open the database, it might startup. However, that wouldnot lead me in ensuring this won't occur again.
That's why I am trying to understand why it should open, so many processes (why spawn so many .flb files?) Any thoughts you have around this?
I will try to restart the OS as the last resort.
Thanks for your help and suggestions.

Java.util.zip.ZipException: Too many open files on Linux
Hi,
We have web application running on Caucho's resin server on jdk 1.5.0_11 and Red hat Linux. We are noticing that java process is running out of file handles within 24-30 hours. We have file limit of 5000 which it consumes in 24 hours throwing 'java.util.zip.ZipException: Too many open files'.
I have made sure all sorts of file handles are closed from application point of view. Here is the snapshot of lsof (list of file handles) from java process. The following list keeps growing until it runs out of limit. Do you have tips/suggestions on how to mitigate this problem (considering we dont want to increase ulimit for this process)? Also, can you make out any thing more from the description of file handles like, are they unclosed POP3 connections or URL connection to external sites?

Runtime.exec - Too Many Open Files
System version : Red Hat Enterprise Linux 2.4.21-47.ELsmp AS release 3 (Taroon Update 8)
JRE version : 1.6.0-b105
Important : the commands described below are launched from a Web application : Apache Tomcat 6.0.10
Hello,
I'm facing a problem already known, but appearantly never really solved ??!! ;)
When I invoke many system commands with the 'Runtime.exec(...)' method, there are open files that are not released (I can see them with the "lsof" system command) .
At the end, the unavoidable "too many open files" Exception.
The lauched commands are "ssh ... " commands.
In the topics relating to this problem, the solution is always to close all Streams / threads and to explicitely invoke the method "Process.destroy()".
My problem is that this is what I do ! And I can't do more...
Here is the code :
Runtime rt = Runtime.getRuntime();
Process process = rt.exec("ssh ...");
// ProcessStreamHolder extends Thread and reads from the InputStream given in constructor...
ProcessStreamHolder errorStream = new ProcessStreamHolder(process.getErrorStream());
ProcessStreamHolder outputStream = new ProcessStreamHolder(process.getInputStream());
errorStream.start();
outputStream.start();
exitValue = process.waitFor();
try {
errorStream.interrupt();
} catch (RuntimeException e) {
logger.warn("...");
try {
outputStream.interrupt();
} catch (RuntimeException e) {
logger.warn("...");
try {
process.getInputStream().close();
} catch (RuntimeException e) {
logger.warn("...");
try {
process.getOutputStream().close();
} catch (RuntimeException e) {
logger.warn("...");
try {
process.getErrorStream().close();
} catch (RuntimeException e) {
logger.warn("...");
process.destroy();Does someone know if my code is wrong or if there's a workaround for me ?
Thanks by advance !
Richard.Don't interrupt those threads. Close the output stream first, then wait for the process to exit, then both threads reading the stdout and stderr of the process should get EOFs, so they should exit naturally, and incidentally close the streams themselves.

"Too many open files" Exception on "tapestry-framework-4.1.1.jar"
When a browser attempts accessing to my webwork, the server opens a certain number of file descriptors to "tapestry-framework-4.1.1.jar" file and don't release them for a while.

These unknown references are sometimes released automatically, but sometimes not.
And I get "Too many open files" exception after using my application for a few hours.
The number of the unknown references increases as I access to my webwork or just hit on "F5" key on my browser to reload it.
I tried different types of browsers to see if I could see any differences in consequence, and in fact it differed by the browser I used.
When viewed by Internet Explorer it increased by 3 for every access.
On the other hand it increased by 7 for each attempt when accessed by FireFox.
I have already tried optimizing the max number of file discriptors, and it solved the "Too many open files" exception.
But stil I'm wondering who actually is opening "tapestry-framework-4.1.1.jar" this many.
Could anyone figure out what is going on?
Thanks in advance.
The following is my environmental version info:
- Red Hat Enterprise Linux ES release 4 (Nahant Update 4)
- Java: 1.5.0_11
- Tomcat: 5.5.20
- Tapestry: 4.1.1Hi,
Cause might The server got an exception while trying to accept client connections. It will try to backoff to aid recovery.
The OS limit for the number of open file descriptor (FD limit) needs to be increased. Tune OS parameters that might help the server to accept more client connections (e.g. TCP accept back log).

Intermittent too many open files error and Invalid TLV error
Post Author: jam2008
CA Forum: General
I'm writing this up in the hopes of saving someone else a couple of days of hair-pulling...
Environment: Crystal Reports XI Enterprise / also runtime via Accpac ERP 5.4
Invalid TLV error in Accpac
"too many open files" error in event.log file
Situation:
Invalid TLV error occurs seemingly randomly on report created in CR Professional 11. Several days of troubleshooting finally lead to the following diagnosis:
This error occurs in a report that contains MORE THAN 1 bitmap image.
The error only shows up after 20 or more reports have been generated sequentially, WITHOUT CLOSING the application that is calling the report. In our case the Invoice Report dialog within Accpac. This same error occurred in a custom 3rd party VB.NET app that also called the report through an Accpac API.after getting this message you need to do 2 things:
1. delete the current workspace because it contains some bad data in one the config files - failure to delete the workspace will result the error message to appear even if trying to upload a single file.
2. add to DTR files in groups - no more than 500 in a single add. -

Thank you, bye,
MarcoHello Marco.
When you try to deploy an EAR weblogic server at the time of deployment unjar's it and compiles the files and so on. Every Operating system has a limit on how many number of files can be opened by a process. If your EAR is big then the number of files which WLS will unjar will also be large hence you hit the limit. By splitting your ear into 2, you are splitting wls task into smaller parts, which means the number of files it unjars at a time is less.
The following note tells what needs to be done to avert this issue.

What have "Too many open Files" to do with FIFOs?
Hi folks.
I've just finished a middleware service for my company, that receives files via a TCP/IP connection and stores them into some cache-directory. An external program gets called, consumes the files from the cache directory and puts a result-file there, which itself gets sent back to the client over TCP/IP.
After that's done, the cache file (and everything leftover) gets deleted.
The middleware-server is multithreaded and creates a new thread for each request connection.
These threads are supposed to die when the request is done.
All works fine, cache files get deleted, threads die when they should, the files get consumed by the external program as expected and so on.
BUT (there's always a butt;) to migrate from an older solution, the old data gets fed into the new system, creating about 5 to 8 requests a second.
After a time of about 20-30 minutes, the service drops out with "IOException: Too many open files" on the very line where the external program gets called.
I sweeped through my code, seeking to close even the most unlikely stream, that gets opened (even the outputstreams of the external process ;) but the problem stays.
Things I thought about:
- It's the external program: unlikely since the lsof-command (shows the "list of open files" on Linux) says that the open files belong to java processes. Having a closer look at the list, I see a large amount of "FIFO" entries that gets bigger, plus an (almost) constant amount of "normal" open file handles.
So perhaps the handles get opened (and not closed) somehwere else and the external program is just the drop that makes the cask flood over.
- Must be a file handle that's not closed: I find only the "FIFO" entries to grow. Yet I don't really know what that means. I just think it's something different than a "normal" file handle, but maybe I'm wrong.
- Must be a socket connection that's not closed: at least the client that sends requests to the middleware service closes the connection properly, and I am, well, quite sure that my code does it as well, but who knows? How can I be sure?
That was a long description, most of which will be skipped by you. To boil it down to some questions:
1.) What do the "FIFO" entries of the lsof-command under Linux really mean ?
2.) How can I make damn sure that every socket, stream, filehandle etc. pp. is closed when the worker thread dies?
Answers will be thanked a lot.
TomThanks for the quick replies.
@BIJ001:
ls -l /proc/<PID>/fdGives the same information as lsof does, namely a slowly but steadily growing amount of pipes
fuserDoesn't output anything at all
Do you make exec calls? Are you really sure stdout and stderr are consumed/closed?Well, the external program is called by
Process p = Runtime.getRuntime().exec(commandLine);and the stdout and stderr are consumed by two classes that subclass Thread (named showOutput) that do nothing but prepending the corresponding outputs with "OUT:" and "ERR" and putting them into a log.
Are they closed? I hope so: I call the showOutput's halt method, that should eventually close the handles.
@sjasja:
Sounds like a pipe.Thought so, too ;)
Do you have the waitFor() in there?Mentioning the waitFor():
my code looks more like:
try {
p = Runtime.getRuntime.exec(...);
outshow = new showOutput(p.getInputStream(), "OUT").start;
errshow = new showOutput(p.getErrorStream(), "ERR").start;
p.waitFor();
} catch (InterruptedException e) {
//can't wait for process?
//better go to sleep some.

}Seems as if the both of you are quite sure that the pipes are actually created by the exec command and not closed afterwards.
Would you deem it unlikely that most of the handles are opened somewhere else and the exec command is just the final one that crashes the prog?
That's what I thought.
Thanks for your time

Weblogic Server Switch over automatically due to too many open files error.
Hi,
I am facing problem in production environment. I am using Weblogic 8.1 SP4 application.

Thanks & Regards,
Suriyaprakash.VSorry for the late resp. Here's what dev suggests be investigated:
I would want to know:
Can they do a "$ORACLE_HOME/bin/dmstool -dump" and
save/compress/send the results?
Are there any errors printed in the Apache error_log while this leak occurs?
The customer could/should re-check their TCP settings, especially the TCP time wait interval and generally follow the TCP settings recommended in Chapter 5 of the iAS Performance Guide for 9.0.2.
Is there anything else interesting/unusual about the site?
Let us know how it goes. -

WLS 10.3.5 on RHEL 5.4, SocketException: Too many open files
Hi
I'm running Weblogic server 10.3.5 on Red Hat Enterprise Linux Server release 5.4 (Tikanga), with Java jdk1.6.0_27.
My order handling application, when receiving client orders, needs to make outbound SOAP calls to fulfill the order. During a performance test, we got following errors:
####<Feb 10, 2012 2:28:41 PM ICT> <Critical> <Server> <KKMOMAPP2> <KKMOMPE2> <DynamicListenThread[Default]> <<WLS Kernel>> <> <> <1328858921806> <BEA-002616> <Failed to listen on channel "Default" on 172.24.106.81:4095, failure count: 1, failing for 0 seconds, java.net.SocketException: Too many open files>
I monitored the java process of this application, when the "Too many open files" error happened, it had 1388 open file descriptors, among which 655 were sockets.
I also monitored the total open file descriptors of the weblogic user account, the count was around 6300 during this error.
These numbers are far smaller than the file limits configured on OS:
- Under weblogic account, ulimit -n shows 65536
- /proc/sys/fs/file-max shows 772591
- Following lines are already in /etc/security/limits.conf
weblogic soft nofile 65536
weblogic hard nofile 65536
weblogic soft nproc 16384
weblogic hard nproc 16384
I did another test using a simple java program to open large number of sockets under weblogic account. It has no problem to open 15,000 sockets. It seems the file descriptor limit is indeed quite high, but for some reasons, the Weblogic process fails even when it has merely 1388 open files. Are there other Linux or Weblogic parameters I should tune? Or anything else I missed?
Thank you very much
NingHi All,
Any help on this issue ?
Thank you,

Actually, the stuff works in interpreted mode.
It's only when having the server partition compiled that this happen.

Hi,
running a server partition that reads a configuration file,
and apparently doen't close it after, I have that exception:
SYSTEM ERROR: System Error: Too many open files, opening '....'with mode
'r'
Class: qqos_FileResourceException
1) Is there such a limit, or does this rely only on the OS one ?
2) How is this error not trapped, as I only got itinteractively, whereas
my server log does a exception trap/segmentation fault,
thanlks

As described in the Technote 10981 some Forte programs (Nodemanager and
router) handle correct the high-file descriptor-use problem. It is possible
that Forte interpreter do it correct too.
