Error description
The FTP server in IBM Sterling B2B Integrator V5.2.5 runs on an adapter container. Once a week, the server becomes slow to respond and eventually unresponsive to the new external connections. This issue occurred when a trading partner uses an FTP Client with resumption and Multi-Part download enabled. The thread dumps (javacores) for the FTP server threads consistently show: "FTPServer-Node1_Thread_30" J9VMThread:0x000000000D3B2E00, j9thread_t:0x00002B27BD5FF590, java/lang/Thread:0x00000006846B88A8, state:R, prio=5 (java/lang/Thread getId:0x59F520, isDaemon:true) (native thread ID:0x794B, native priority:0x5, native policy:UNKNOWN, vmstate:R, vm thread flags:0x00000001) (native stack address range from:0x00002B27AFB83000, to:0x00002B27AFBC4000, size:0x41000) CPU usage total: 110.877181117 secs Heap bytes allocated since last GC cycle=0 (0x0) Java callstack: at java/io/FileInputStream.readBytes(Native Method) at java/io/FileInputStream.read(FileInputStream.java:286(Compiled Code)) at java/io/BufferedInputStream.fill(BufferedInputStream.java:247(Co mpiled Code)) at java/io/BufferedInputStream.read1(BufferedInputStream.java:287(C ompiled Code)) at java/io/BufferedInputStream.read(BufferedInputStream.java:346(Co mpiled Code)) (entered lock: java/io/BufferedInputStream@0x00000006888C2530, entry count: 1) at com/sterlingcommerce/woodstock/workflow/DocumentInputStream.read FromFS(DocumentInputStream.java:199(Compiled Code)) at com/sterlingcommerce/woodstock/workflow/DocumentInputStream.read (DocumentInputStream.java:180(Compiled Code)) at java/io/InputStream.skip(InputStream.java:245(Compiled Code)) at com/sterlingcommerce/woodstock/services/ftpserver/server/Documen tOutputStreamWrapper.seek(DocumentOutputStreamWrapper.java:120(C ompiled Code)) at com/sterlingcommerce/woodstock/services/ftpserver/server/FtpMail boxDataStore.openRead(FtpMailboxDataStore.java:1146(Compiled Code)) at com/sterlingcommerce/woodstock/services/ftpserver/server/FtpMail boxDataStore.open(FtpMailboxDataStore.java:1001(Compiled Code)) at com/sterlingcommerce/woodstock/services/ftpserver/server/FtpFile .open(FtpFile.java:189(Compiled Code)) at com/sterlingcommerce/woodstock/services/ftpserver/server/FtpComm and.openFile(FtpCommand.java:2453(Compiled Code)) at com/sterlingcommerce/woodstock/services/ftpserver/server/FtpComm and.handleRETRCommand(FtpCommand.java:1324(Compiled Code)) at sun/reflect/GeneratedMethodAccessor98.invoke(Bytecode PC:83(Compiled Code)) at sun/reflect/DelegatingMethodAccessorImpl.invoke(DelegatingMethod AccessorImpl.java:56(Compiled Code)) at java/lang/reflect/Method.invoke(Method.java:620(Compiled Code)) at com/sterlingcommerce/woodstock/services/psclientcommon/statemach ine/Command.execute(Command.java:91(Compiled Code)) at com/sterlingcommerce/woodstock/services/psclientcommon/statemach ine/StateMachine.handleCommand(StateMachine.java:82(Compiled Code)) at com/sterlingcommerce/woodstock/services/psclientcommon/statemach ine/StateMachine.handleCommand(StateMachine.java:55(Compiled Code)) at com/sterlingcommerce/woodstock/services/psclientcommon/Session.h andleCommand(Session.java:137(Compiled Code)) at com/sterlingcommerce/woodstock/services/ftpserver/server/FtpSess ion.handleCommand(FtpSession.java:497(Compiled Code)) at com/sterlingcommerce/woodstock/services/psclientcommon/ftp/Contr olConnection.processInput(ControlConnection.java:305(Compiled Code)) at com/sterlingcommerce/woodstock/services/psclientcommon/ftp/Contr olTransferAgent.handleControlReceiveEvent(ControlTransferAgent.j ava:117(Compiled Code)) at com/sterlingcommerce/woodstock/services/psclientcommon/ftp/Contr olTransferAgent.access$100(ControlTransferAgent.java:31(Compiled Code)) at com/sterlingcommerce/woodstock/services/psclientcommon/ftp/Contr olTransferAgent$2.run(ControlTransferAgent.java:83(Compiled Code)) at com/sterlingcommerce/perimeter/api/scheduler/DebugPooledExecutor $Worker.run(DebugPooledExecutor.java:786(Compiled Code)) at java/lang/Thread.run(Thread.java:798(Compiled Code))
