[jira] Created: (FTPSERVER-403) FTP would periodically hang in MDC
FTP would periodically hang in MDC
----------------------------------
Key: FTPSERVER-403
URL: https://issues.apache.org/jira/browse/FTPSERVER-403
Project: FtpServer
Issue Type: Bug
Components: Core, Server
Affects Versions: 1.0.5, 1.0.4, 1.0.3
Environment: Encountered it both on Linux and FreeBSD, both on Sun JVM 1.6 and OpenJDK 6.
Reporter: ArtemGr
FTP works fine for the most time but once in a while (depended on how often the FTP is used) it would hang, consuming 100% CPU, in
java.util.HashMap.removeEntryForKey (HashMap.java:586)
java.util.HashMap.remove (HashMap.java:555)
org.slf4j.helpers.BasicMDCAdapter.remove (BasicMDCAdapter.java:91)
org.slf4j.MDC.remove (MDC.java:156)
org.apache.mina.filter.logging.MdcInjectionFilter.filter (MdcInjectionFilter.java:141)
org.apache.mina.filter.util.CommonEventFilter.messageSent (CommonEventFilter.java:75)
org.apache.mina.core.filterchain.DefaultIoFilterChain.callNextMessageSent (DefaultIoFilterChain.java:462)
org.apache.mina.core.filterchain.DefaultIoFilterChain.access$1300 (DefaultIoFilterChain.java:46)
org.apache.mina.core.filterchain.DefaultIoFilterChain$EntryImpl$1.messageSent (DefaultIoFilterChain.java:802)
org.apache.mina.filter.codec.ProtocolCodecFilter.messageSent (ProtocolCodecFilter.java:287)
org.apache.mina.core.filterchain.DefaultIoFilterChain.callNextMessageSent (DefaultIoFilterChain.java:462)
org.apache.mina.core.filterchain.DefaultIoFilterChain.access$1300 (DefaultIoFilterChain.java:46)
org.apache.mina.core.filterchain.DefaultIoFilterChain$EntryImpl$1.messageSent (DefaultIoFilterChain.java:802)
org.apache.mina.core.filterchain.IoFilterEvent.fire (IoFilterEvent.java:80)
org.apache.mina.core.session.IoEvent.run (IoEvent.java:63)
org.apache.mina.filter.executor.OrderedThreadPoolExecutor$Worker.runTask (OrderedThreadPoolExecutor.java:780)
org.apache.mina.filter.executor.OrderedThreadPoolExecutor$Worker.runTasks (OrderedThreadPoolExecutor.java:772)
org.apache.mina.filter.executor.OrderedThreadPoolExecutor$Worker.run (OrderedThreadPoolExecutor.java:714)
The only MDC-related code that our application adds is the following in the UserManager.authenticate implementation:
Map context = MDC.getCopyOfContextMap();
if (context != null) System.out.println ("FTP user logged in: " + context);
return user;
Seems like a synchronization issue to me.

-----------------------------------
I'm using slf4j-api-1.6.1.jar and slf4j-jdk14-1.6.1.jar for some time.
Went thru several MINA and slf4j upgrades over time (while tracking the FTPSERVER SVN) in hopes that it will go away.

The only MDC-related code that our application adds is the following in the UserManager.authenticate implementation:
Map context = MDC.getCopyOfContextMap();
if (context != null) System.out.println ("FTP user logged in: " + context);
return user;
Seems like a synchronization issue to me.
Affects Version/s: 1.0.6
Still seeing it in 1.0.6, Mina 2.0.4.
