mattekure Posted July 30, 2017 Share Posted July 30, 2017 This morning I got the error "Call Traces found on Server", but I dont even know where to begin to look. I have attached diagnostics file from this morning. Along with the "Call Trace" error, there was a bunch of "Template URL for docker is missing" errors. tower-diagnostics-20170730-1009.zip Link to comment
brando56894 Posted July 31, 2017 Share Posted July 31, 2017 The call traces exist in the kernel ring buffer, to view it use dmesg from the command line. I prefer to use the -HT flags so that it uses a pager and give human readable timestamps. This is most likely caused by either running out of RAM or working your CPU too hard. Were you running a VM? What's your hardware specs? Link to comment
wisebear Posted August 8, 2017 Share Posted August 8, 2017 I want to use an existing topic as I am also getting Call Traces errors. Attached you can find diagnostic files. From the system log I can see errors like this: python[12239]: segfault at 2aadb4b2dff8 ip 00002aadb00d96d1 sp 00002aadb4b2e000 error 6 in libpython2.7.so.1.0[2aadb006b000+342000] and call trace like this Aug 5 21:52:47 unRAID kernel: CPU: 2 PID: 20342 Comm: Plex Media Serv Not tainted 4.9.30-unRAID #1 Aug 5 21:52:47 unRAID kernel: Hardware name: HP ProLiant MicroServer Gen8, BIOS J06 11/02/2015 Aug 5 21:52:47 unRAID kernel: ffffc900037fbb28 ffffffff813a4a1b 0000000000000001 0000000000000000 Aug 5 21:52:47 unRAID kernel: ffffc900037fbbb8 ffffffff810cb5b1 024201ca810c9d8d ffffffff8193d4e2 Aug 5 21:52:47 unRAID kernel: ffffc900037fbb50 0000000000000010 ffffc900037fbbc8 ffffc900037fbb68 Aug 5 21:52:47 unRAID kernel: Call Trace: Aug 5 21:52:47 unRAID kernel: [<ffffffff813a4a1b>] dump_stack+0x61/0x7e Aug 5 21:52:47 unRAID kernel: [<ffffffff810cb5b1>] warn_alloc+0x102/0x116 Aug 5 21:52:47 unRAID kernel: [<ffffffff810cbb67>] __alloc_pages_nodemask+0x541/0xc71 Aug 5 21:52:47 unRAID kernel: [<ffffffff810c4d78>] ?
