        extract of the 277942.1 note on metalink:

        perhaps (!!) an explanation :
        The crash no longer occurs when Reports Server tracing is switched off. This may be due to the size of the trace file and that there was insufficient disk space / memory/cpu available to create it.

        Switch off Reports Server tracing by commenting out the xml tag relating to tracing in the Reports Server conf file.
        Change
        <trace traceOpts="trace_all"/>
        to
        <!--trace traceOpts="trace_all"/-->

          I played with the trace option but it didn't work, I think the problem is with the size of the data, report engine crashes while formatting the report.

          I don't know what is causing this problem

          thanks for your help

            Have you raised a TAR ?

            Have you switched tracing on in the server to see what it's doing ?

              Thanks for your reply, we did open tar with oracle but it's is hanging with them for the last 3 weeks.

              It's crashing on a stream function (processing an input stream)

              Please mail me if you have any solutions for this problem, may be some settings are not correct.

                I find the warning message in the logs:
                05/05/28 17:20:19 REP-56097: Engine rwEng-0 callback timeout

                Could anybody tell me why?
                Thanks in advance!

                  Hi

                  Just a thought

                  I can cause my report server to crash quite easily
                  ( not with your frm error ) but reason and solution may help

                  Default cache size is 50mb on 9i report server
                  If i change to 1mb and run a report which generates a cache file > 1mb ( a simple graph in this case ), form calling report will hang along with report server
                  Change cache to say 10Mb, restart report server and report runs without any problems

                  Can see the report failing in reports/rwservlet web page
                  Look in <appserver home>/reports/cache to see files created

                  edit <appserver home>/reports/conf/<report server>.conf
                  and look at cache size value

                  Hope this helps

                  Ian

                    I've been having exactly the same problem.
                    When I run the report and limit the amount of data, it works fine.
                    When I go over some amount, it fails.
                    I've played with the cache (and numerous other settings, including trace) and nothing has resolved this.
                    btw, I'm using this to create a delimited file, and the headers for thet file do show up in the cache directory, but no data.

                    Anyone have any luck so far?
                    thanks!

                      Joel,
                      did you get the solution?

                      I am having the same exact problem.
                      anybody.... help please..
                      thanks-

                        The best way to track this down is to set trace-level debug on and see what is causing the problem. Lots of things can cause 56048. Reports has bugs in it left over from the age of dinosaurs. You just have to work around them...

                          problem is with page numbering in huge reports (for example in text field):
                          Page &<PageNumber> of &<TotalPages>
                          When use only
                          Page &<PageNumber>
                          report generate ok.

                            I may have found a solution for this. I just had this problem and I looked through the trace files. Here is the culprit:

                            [2007/6/6 2:19:4:613] Error 50103 (C Engine): 14:19:04 ERR REP-0069: Internal error

                              Srini, Make sure you are not writing over 65, 536 rows to a spreadsheet. Did you find any such issue while generating PDFs?
                              Thanks

                                It could be a bug, try upgrading.
