We are using MQworkflow 3.5 in solaris.

We occasionally get the below EOF errors while browsing from our UPES Queue defined in Workflow QueueManager
java.io.EOFException
at com.ibm.mq.MQMessage.readConvertedString(MQMessage.java:1943)
at com.ibm.mq.MQMessage.readString(MQMessage.java:960)
at com.jpmorgan.cc.common.utils.workflowmanager.QueueAdapter.browseMessage(QueueAdapter.java:192)

The code snippet doing the read is below
browseMsgOptions = new MQGetMessageOptions();
browseMsgOptions.options = MQC.MQGMO_NO_WAIT | MQC.MQGMO_BROWSE_NEXT;
MQMessage retrievedMessage = new MQMessage();
queue.get(retrievedMessage, browseMsgOptions);
message = retrievedMessage.readString(retrievedMessage.getMessageLength());

Question:
Will the EOFException during queue browse occur due to a smaller message buffer size in the queue or channel. Our current settings are
qmgr maxmsgl(4194304)
qlocal(EXCINPUTQ) maxmsgl(4194304)
channel (FMCQM.CL.TCP) chltype(SVRCONN) maxmsgl(9999999)
channel (FMCQM.CL.TCP) chltype(CLNTCONN) maxmsgl(9999999)

The Above Error occurs in the below code snippet
browseMsgOptions = new MQGetMessageOptions();
browseMsgOptions.options = MQC.MQGMO_NO_WAIT | MQC.MQGMO_BROWSE_NEXT;
MQMessage retrievedMessage = new MQMessage();
queue.get(retrievedMessage, browseMsgOptions);
message = retrievedMessage.readString(retrievedMessage.getMessageLength());
