There are two interesting parts to this error. The 1st is: /usr/sbin/carod:894: FutureWarning: hex/oct constants > sys.maxint will return positive values in Python 2.4 and up session.message_flow(data.amqp_config['work_queue_name'], 0, 0xFFFFFFFF) /usr/sbin/carod:895: FutureWarning: hex/oct constants > sys.maxint will return positive values in Python 2.4 and up session.message_flow(data.amqp_config['work_queue_name'], 1, 0xFFFFFFFF) These warnings are a part of python2.3 according to the thread: http://mail.python.org/pipermail/python-dev/2002-November/030583.html The above thread also gives a few solutions to solve the situation for a few different cases. The exception comes from oxFFFFFFFF being larger than sys.maxint on 32-bit systems, causing the value to be negative. There are a number of overflow fixes that have gone into RHEL4.9 (486329, 486330, 455008) that could have caused this to pop up. 0xFFFFFFFF is a special value in amqp, and in the instance in carod is setting an unlimited message size for messages received. The fix is to pass the value with a trailing L (0xFFFFFFFFL) Fixed on master.

Sorry, it was bug in our low latency test client. --> CLOSE as NOTABUG Sorry wrong bug :( It's working now. --> ASSIGNED --> VERIFIED An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on therefore solution and/or where to find the updated files, please follow the link below.

Description of problem: I've configured low latency on RHEL 5.6/4.9 x i386/x86_64 and carod ends with exception only on RHEL 4.9 i386. Exception: $ carod -l /usr/sbin/carod:894: FutureWarning: hex/oct constants > sys.maxint will return positive values in Python 2.4 and up session.message_flow(data.amqp_config['work_queue_name'], 0, 0xFFFFFFFF) /usr/sbin/carod:895: FutureWarning: hex/oct constants > sys.maxint will return positive values in Python 2.4 and up session.message_flow(data.amqp_config['work_queue_name'], 1, 0xFFFFFFFF) 01/28 13:29:39 INFO: Starting up Traceback (most recent call last): File "/usr/sbin/carod", line 1085, in ? sys.exit(main()) File "/usr/sbin/carod", line 1014, in main connect_to_broker(share_data, broker) File "/usr/sbin/carod", line 894, in connect_to_broker session.message_flow(data.amqp_config['work_queue_name'], 0, 0xFFFFFFFF) File "/usr/lib/python2.3/site-packages/qpid/generator.py", line 25, in <lambda> method = lambda self, *args, **kwargs: self.invoke(op, args, kwargs) File "/usr/lib/python2.3/site-packages/qpid/session.py", line 138, in invoke return self.do_invoke(op, args, kwargs) File "/usr/lib/python2.3/site-packages/qpid/session.py", line 171, in do_invoke self.send(cmd) File "/usr/lib/python2.3/site-packages/qpid/session.py", line 204, in send self.sender.send(cmd) File "/usr/lib/python2.3/site-packages/qpid/session.py", line 255, in send ch.connection.write_op(cmd) File "/usr/lib/python2.3/site-packages/qpid/connection.py", line 195, in write_op self.op_enc.write(op) File "/usr/lib/python2.3/site-packages/qpid/framing.py", line 214, in write enc = self.encode_command(op) File "/usr/lib/python2.3/site-packages/qpid/framing.py", line 239, in encode_command sc.write_fields(cmd) File "/usr/lib/python2.3/site-packages/qpid/codec010.py", line 360, in write_fields enc(value) File "/usr/lib/python2.3/site-packages/qpid/codec010.py", line 131, in write_uint32 raise CodecException("Cannot encode %d as uint32" % n) qpid.codec010.CodecException: Cannot encode -1 as uint32 Version-Release number of selected component (if applicable): python-wallabyclient-3.9-2.el4 condor-job-hooks-1.4-6.el4 qpid-java-client-0.7.946106-14.el4 qpid-cpp-server-ssl-0.7.946106-27.el4 qpid-cpp-server-xml-0.7.946106-27.el4 qpid-cpp-client-devel-docs-0.7.946106-27.el4 condor-debuginfo-7.4.5-0.7.el4 python-condorutils-1.4-6.el4 python-qpid-0.7.946106-15.el4 condor-wallaby-client-3.9-2.el4 condor-low-latency-1.1-0.2.el4 qpid-cpp-client-0.7.946106-27.el4 qpid-cpp-server-0.7.946106-27.el4 qpid-cpp-client-ssl-0.7.946106-27.el4 qpid-java-common-0.7.946106-14.el4 qpid-java-example-0.7.946106-14.el4 qpid-cpp-server-devel-0.7.946106-27.el4 qpid-tools-0.7.946106-12.el4 qpid-tests-0.7.946106-1.el4 qpid-cpp-mrg-debuginfo-0.7.946106-27.el4 condor-7.4.5-0.7.el4 rh-tests-distribution-MRG-Messaging-qpid_common-1.6-56 qpid-cpp-client-devel-0.7.946106-27.el4 qpid-cpp-server-store-0.7.946106-27.el4 How reproducible: 100% Steps to Reproduce: 1. set up low latency by remote configuration 2. restart condor 3. watch MasterLog Actual results: carod ends with unhandled exception. Expected results: carod will not end with exception and will properly communicate with broker and will work its job.
