https://bugzilla.novell.com/show_bug.cgi?id=718973#c0 Summary: Mono crashes on file locking with multiple threads accessing the same file Classification: Mono Product: Mono: Runtime Version: 2.10.x Platform: i386 OS/Version: Linux Status: NEW Severity: Critical Priority: P5 - None Component: io-layer AssignedTo: mono-bugs@lists.ximian.com ReportedBy: e...@rantek.dk QAContact: mono-bugs@lists.ximian.com Found By: --- Blocker: --- Created an attachment (id=451774) --> (http://bugzilla.novell.com/attachment.cgi?id=451774) Repro code including my stacktraces. User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:7.0) Gecko/20100101 Firefox/7.0 My app started crashing with a SIGABRT while using a 3rd party logging lib after some hours, we think we have nailed it down to the way that mono locks (oplock) the file. I am using mono 2.6.7 on a Debian Squeeze, we have tried to reproduce the exact error that we got, but I have unfortunately been unable reproduce it exactly. The error that mono 2.6.7 prints on my repro is not very informative and I though that I try a newer version, unfortunately its much worse in 2.10.5 (tested with ubuntu 11.10) there my repro code crashes after just a few writes. Please let me know if there is anything that you need to fix this as it quite a big deal for me and mono in general.. I hope that severity is correct as mono crashes.. Cheers Esben Reproducible: Always Steps to Reproduce: I have attached my repro code, its not the exact stacktrace that I get in my app, but there is some problem anyways. Just compile and run it. With v2.10.5 it fails after a few writes with 10 threads, with v2.6.7 it can be a while, but forcing the threads to 50 speeds it up. Actual Results: It crashes, with a SIGABRT.. Expected Results: It should continue in a endless loop writing to the same file.. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
