<p>Well, a signal 11 can be caused by several different things, including
some messed up pointer stuff in a C library, or just bad memory on your
computer. I think a memory test would be a good first step.</p>
<p>If the memory checks clean, running git-annex in gdb and getting a stack
trace after a crash may help.</p>
Same problem with git-annex 8.20210223http://git-annex.branchable.com/bugs/git-annex_died_of_signal_11_when_syncing_content/comment_2_e920f624ccf2e3a9c71a00105ebc3595/git-annex.visiteur2021-10-20T19:09:29Z2021-10-20T19:09:29Z
<p>I have exactly the same problem with Debian 11 and git-annex 8.20210223. In kernel.log I can see</p>
<blockquote><p>traps: git-annex[91341] general protection fault ip:3c6be67 sp:7ffd7afd26f8 error:0 in git-annex[400000+3a78000]</p></blockquote>
<p>I've done a memtest86 on my memory and nothing appended.</p>
<p>Oddly, I have another machin with same versions of OS and git-annex, but it does not reproduce the problem. The bigger difference between the two machines is that machine with problem run on ZFS. Is it possible that the problem comes from that?</p>

<p>Since the vast number of places git-annex runs do not have this problem, I
don't think we can draw any conclusions about differences between your 2
machines.</p>
<p>Memory issue still seems like the most likely bet.</p>
<p>Are you able to reproduce the problem repeatedly?</p>

<p>Yes the problem occurs each time I want to do git annex get . on a repository with about 20 000 files.</p>
<p>As i say, I've perfom memtest86 (several times) and memtester (several times) without any problem. Do you think it could be hardware problem despite these results ?</p>
<p>You suggest using gdb. I get</p>
<p>Thread 1 "git-annex" received signal SIGSEGV, Segmentation fault.
0x0000000003c6be67 in ?? ()</p>
<p>(gdb) backtrace</p>
<h1>0 0x0000000003c6be67 in ?? ()</h1>
<h1>1 0x0000000000000000 in ?? ()</h1>
<p>which is not very helpful. Do you have any advices to investigate?</p>
