Synergy 1.7.5 Crashed In Ubuntu

3 posts in this topic

I came into the office this morning and found I was unable to move the mouse from my Ubuntu 14.04 Desktop (running the Synergy Server 1.7.5) to my Windows 7 Laptop (Running Synergy Client 1.7.5). I am currently watching Ubuntu's apport thing spinning away after I asked to "Examine locally" thinking that as I do not download Synergy from Ubuntu it might not generate a valid report and just end up hiding the .ops somewhere unhelpful. A second click on the "Examine locally" button too my me to a notification stating: [quote]The crashed program seems to use third-party or local libraries: /home/thomasthorne/.synergy/plugins/libns.so It is highly recommended to check if the problem persists without those first. Do you want to continue the report process anyway?[/quote] I have chosen to proceed and try examining the stack trace. Meanwhile my server must have restarted becase I can access the laptop again. After a few jittery moments that has reported the Windows side synergyc.exe has stopped working. Ahh gdb is back and says... [code]WARNING: /home/thomasthorne/.synergy/plugins/libns.so is needed, but cannot be mapped to a package dynamically loaded /usr/lib/x86_64-linux-gnu/libXfixes.so.3.1.0 needs package libxfixes3, queueing Calling gdb command: gdb --ex 'set debug-file-directory /tmp/apport_sandbox_bxuX8K/usr/lib/debug' --ex 'set solib-absolute-prefix /tmp/apport_sandbox_bxuX8K' --ex 'file "/tmp/apport_sandbox_bxuX8K//usr/bin/synergys"' --ex 'core-file /tmp/apport_core_xYGij4' GNU gdb (Ubuntu 7.7.1-0ubuntu5~14.04.2) 7.7.1 Copyright (C) 2014 Free Software Foundation, Inc.

()[/code] Hmm I don't think this is going to very helpful unless anyone can suggest what I should do next. I am in the office for about 4 more hours and then I am away for two weeks. Hopefully some debug files will be here when I get back or someone can nudge me in the next couple of hours with a suggestion of what to do.

I don't know if the Windows problem will be related or not. If I "Send information" to Microsoft will it find its way to you in a helpful manner? I can try an upload the .tmp.hdmp file here if that would be more helpful.

This is happening to me as well and I'm using LM17.3. It will just crash and from Win7 say that client is dead. dmesg [ 3715.623154] synergyc[3592]: segfault at 7f76f8021000 ip 00007f76fe7eb9e0 sp 00007f770002b998 error 4 in libcrypto.so.1.0.0[7f76fe770000+1b2000] [ 4981.086665] synergyc[4076]: segfault at 10 ip 0000000000455a38 sp 00007f86bf7fddd0 error 4 in synergyc[400000+a6000]
