Segfault Error Codes
duplicate of stackoverflow.com/questions/2179403/… –Charles Duffy Mar 31 '10 at 0:21 add a comment| 3 Answers 3 active oldest votes up vote 43 down vote accepted Hmm. 4 is EINTR (interrupted system call). It may be that libQtWebKit is habitually mishandling that error, or it may be that there's something else that's going on. If this were a program, not a shared library Run addr2line -e yourSegfaultingProgram 00007f9bebcca90d (and repeat for the other instruction pointer values given) to see where the error is happening. Better, get a debug-instrumented build, and reproduce the problem under a debugger such as gdb. Since it's a shared library You're hosed, unfortunately; it's not possible to know where the libraries were placed in memory by the dynamic linker after-the-fact. Reproduce the problem under gdb. What the error means Here's the breakdown of the fields: address (after the at) - the location in memory the code is trying to access (it's likely that 10 and 11 are offsets from a pointer we expect to be set to a valid value but which is instead pointing to 0) ip - instruction pointer, ie. where the code which is trying to do this lives sp - stack pointer error - An error code for page fau

you get. So you have a message like the following: segfault at bfea3fec ip 080ee07e sp bfea3fa0 error 6 You might already know that ip means instruction pointer and https://rgeissert.blogspot.com/2013/07/explaining-segmentation-fault-errors.html sp means stack pointer and as such the addresses that follow them are the values in those registers. But what does the error number mean? The error number, or code, actually gives you https://forums.opensuse.org/showthread.php/474733-SEGFault-on-Kernel(-)-ext4(-)-or-something-like-that a better explanation of what the cause of the segfault is. The number's bits are flags describing the error and are architecture-dependent. For x86/x86_64 I just wrote an online converter/decoder that you can use segfault error to explain the segfault error code. As an example, the above error code is explained as: The cause was a user-mode write resulting in no page being found. And the common error 4: The cause was a user-mode read resulting in no page being found.(also known as a null pointer dereference). Enjoy.

The setup is my home server, with 3 HDDs, NFS and SMB. Up to the point that the problem started, I had no issues. However, during the last couple of weeks, I see a really frustrating issue that really causes me a headache and a completely unstable system. What I see is that the systems becomes un-responsive, the HTTP service is not OK, the most importantly, the file systems are not OK (file copies of files are failed with no apparent reason, copies are not completed etc). Although fsck reports no errors, I see the following filling the var/log/messages: Message from syslogd@localhost at Apr 24 22:35:43 ... kernel:[83634.354593] init[1]: segfault at 0 ip 0804c7f6 sp bfb94db0 error 4 in init[8048000+9000] Message from syslogd@localhost at Apr 24 22:36:13 ... kernel:[83664.385153] init[1]: segfault at 0 ip 0804c7f6 sp bfb94db0 error 4 in init[8048000+9000] Message from s
