Server aborting Version-Release number of selected component (if applicable): XFree86 4.2.1-21 How reproducible: Sometimes Steps to Reproduce: 1.start matlab scripts with making plots 2.takes several hours to crash the system 3. Additional info:
Please attach your X server log file and config file to the bug report using the bugzilla file attachment feature. Also attach your kernel log file. Once this information is available, someone can examine it for clues. Be sure that the log file attached is from after the problem occurs, by backing up a copy while X is not running. I don't have access to Matlab, so I'll need your assistance to try and narrow this down to something troubleshootable.

the log file you've attached is incomplete and appears to be captured via shell redirection. Please attach /var/log/XFree86.0.log Also, you didn't attach the kernel log file, please attach /var/log/messages TIA

Mike, I don't know if this is useful given that RH 8 has hit EOL, but: We're seeing similar behavior (and similar logfiles) on an SMP system running XFree86-4.2.1-23. Running some of our code based on ROOT (http://root.cern.ch) eventually causes a signal 11 to be caught by the server. I'm going to upgrade the kernel and try and create a reproducible executable if you guys are interested. - B
Hi Burt, Thanks for your bug update. Unfortunately, as you mention above, Red Hat Linux 8.0 has reached it's supported end of life cycle. The products that we currently support, have XFree86 4.3.0 (in the case of Red Hat Enterprise Linux 3, Red Hat Linux 9, and Fedora Core 1), or XFree86 4.1.0 in the case of Red Hat Enterprise Linux 2.1 and Red Hat Advanced Server 2.1. My recommendation for an officially supported solution, would be if possible, to upgrade to one of our OS products/projects from the above, which ships with XFree86 4.3.0 and see if the problem is resolved in one of these newer OS releases. Red Hat Linux 9 will also be going end of life fairly soon, at the end of April if I recall correctly, so if you'd like to just test 4.3.0 out to see if it works effectively, Fedora Core 1 might be the best option for testing purposes in the short term. Long term, Red Hat Enterprise Linux 3 may turn out to be a more effective solution path for you, as the support life cycle of the RHEL 3 line of products is 5 years from the initial date of release. I'm going to set the status of the report to "WONTFIX" for now, because this OS release is not supported any longer, however if you are able to reproduce this problem still under one of the supported OS releases with XFree86 4.3.0, please reopen the report and we can re-examine the issue in greater detail. Thanks again for the feedback Burt.
