Threads locked while calling SmbFile.getSecurity
by Marc Brette-2
::
Rate this Message:
I have an issue where 16 threads calling SmbFile.getSecurity are blocked. When I have only 15 threads, it works fine (note that each thread accesses a different document, but on the same server).
I use JCIFS 1.2.21. And tested on different shared drives (with and without credentials). I initially tested with 1.2.18 with a more complex example so I guess it s not specific to the JCIFS version. Is it something known ? I saw some thread talking about deadlock in jcifs but it seemed to be in situation unlikely to occur in reality. Here is my code: import java.util.List; import java.util.Arrays; import jcifs.smb.SmbFile; import jcifs.smb.NtlmPasswordAuthentication; public class TestDeadlock { static { System.setProperty("java.protocol.handler.pkgs", "jcifs"); } public static void main(String[] args) throws InterruptedException { final List<String> dataset = Arrays.asList( "smb://frgr1dev1/Y_Drive/Documentation/javadocs/ant/ant 1.6.2 api/org/apache/tools/zip/package-frame.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/ant/ant 1.6.2 api/org/apache/tools/ant/taskdefs/optional/ejb/BorlandDeploymentTool.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/ant/ant 1.6.2 api/org/apache/tools/ant/types/Reference.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/jdk/jdk1.3.1/javax/rmi/package-use.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/jdk/jdk1.3.1/java/io/FilterOutputStream.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/jdk/jdk1.3.1/javax/accessibility/AccessibleTableModelChange.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/jdk/jdk1.4.2/org/omg/stub/java/" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/jdk/jdk1.3.1/javax/transaction/InvalidTransactionException.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/ant/ant 1.6.2 api/org/apache/tools/ant/taskdefs/optional/junit/DOMUtil.NodeListImpl.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/jdk/jdk1.4.2/java/awt/geom/AffineTransform.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/jdk/jdk1.3.1/javax/naming/ldap/package-frame.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/jdk/jdk1.3.1/java/awt/Shape.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/jdk/jdk1.4.2/javax/transaction/xa/package-summary.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/ant/ant 1.6.2 api/org/apache/tools/ant/taskdefs/optional/script/package-summary.html" , "smb://frgr1dev1/Y_Drive/Documentation/javadocs/jdk/jdk1.4.2/javax/net/ServerSocketFactory.html"); int start = 0; int end = 15; Thread[] workers = new Thread[end - start]; for (int i = start; i < end; i++) { final String url = dataset.get(i); workers[i - start] = new Thread(new Runnable() { public void run() { try { SmbFile f = new SmbFile(url); System.out.println(url + " security = " + f.getSecurity(true)); //This trace never shows up } catch (Throwable e) { e.printStackTrace(); } } }); } for (Thread worker : workers) { worker.start(); } for (Thread worker : workers) { worker.join(); } } } Here is an extract of the threads stacktrace dump: "Thread-4" prio=6 tid=0x0033dde8 nid=0x64d4 in Object.wait() [0x031bf000..0x031bf9e8] at java.lang.Object.wait(Native Method) - waiting on <0x2465e260> (a [Ljava.lang.Object;) at java.lang.Object.wait(Object.java:474) at jcifs.smb.BufferCache.getBuffers(BufferCache.java:55) - locked <0x2465e260> (a [Ljava.lang.Object;) at jcifs.smb.SmbTransport.send(SmbTransport.java:547) at jcifs.smb.SmbSession.send(SmbSession.java:239) - locked <0x2467f780> (a java.lang.Object) at jcifs.smb.SmbTree.send(SmbTree.java:109) at jcifs.smb.SmbFile.send(SmbFile.java:695) at jcifs.smb.TransactNamedPipeOutputStream.write(TransactNamedPipeOutputStream.java:65) at jcifs.dcerpc.DcerpcPipeHandle.doSendFragment(DcerpcPipeHandle.java:59) at jcifs.dcerpc.DcerpcHandle.sendrecv(DcerpcHandle.java:164) at jcifs.dcerpc.msrpc.LsaPolicyHandle.<init>(LsaPolicyHandle.java:34) at jcifs.smb.SID.resolveSids0(SID.java:136) at jcifs.smb.SID.resolveSids(SID.java:179) at jcifs.smb.SmbFile.processAces(SmbFile.java:2774) at jcifs.smb.SmbFile.getSecurity(SmbFile.java:2808) at TestDeadlock$1.run(TestDeadlock.java:84) at java.lang.Thread.run(Thread.java:595) "Thread-3" prio=6 tid=0x0033dc60 nid=0x4494 waiting for monitor entry [0x0317f000..0x0317fce8] at jcifs.smb.SmbTree.treeConnect(SmbTree.java:128) - waiting to lock <0x2467f780> (a java.lang.Object) at jcifs.smb.SmbTree.send(SmbTree.java:64) at jcifs.smb.SmbFile.send(SmbFile.java:695) at jcifs.smb.TransactNamedPipeOutputStream.write(TransactNamedPipeOutputStream.java:65) at jcifs.dcerpc.DcerpcPipeHandle.doSendFragment(DcerpcPipeHandle.java:59) at jcifs.dcerpc.DcerpcHandle.sendrecv(DcerpcHandle.java:164) at jcifs.dcerpc.msrpc.LsaPolicyHandle.<init>(LsaPolicyHandle.java:34) at jcifs.smb.SID.resolveSids0(SID.java:136) at jcifs.smb.SID.resolveSids(SID.java:179) at jcifs.smb.SmbFile.processAces(SmbFile.java:2774) at jcifs.smb.SmbFile.getSecurity(SmbFile.java:2808) at TestDeadlock$1.run(TestDeadlock.java:84) at java.lang.Thread.run(Thread.java:595) ... other threads stack traces are similar to "Thread-3" above.

Small change: it is not 16 threads but 15 threads as reflected in the code example.

I think you're hitting jcifs.smb.maxBuffers which defaults to 16.
But I have to wonder how you're getting into that scenario and if increasing that value is the right thing to do.

Hi Mike,
On another machine, I actually hit the issue with only 14 threads. It seems this is machine dependent. Do you think about a work-around so that I could avoid this limit ? Note: I didn't try the new versions you shipped since, but it didn't seem to solve the issue. --Marc

If you never use more threads than twice the number of buffers then I think you should be fine. So if you want to use 10 threads, set maxBuffers to 25, for 100 threads set maxBuffers to 105, ... etc. Note that using a lot of threads does not necessarily equate to more work getting done. Unless your network is slow, I've found that each server can only handle about two threads crawling it at the same time. This deadlock is related to the other connect / disconnect deadlock. At least I think it would be easy to fix if we used a ConditionVariable class instead of synchronized blocks. Mike -- Michael B Allen PHP Active Directory SPNEGO SSO http://www.ioplex.com/ |

Thanks. It solves my issue at least on my machine.
(Note: another work-around was to synchronize the call to getSecurity so that only one thread called it). I also saw that a similar problem was reported here http://lists.samba.org/archive/jcifs/2007-February/007044.html and that you already answered there (I ddin't see this until today). So thanks for taking the time to answer again. On Tue, Aug 5, 2008 at 4:31 PM, Michael B Allen <ioplex@...> wrote:
