pilerimport - segmentation fault

[Mark Clarke]

Hi there,

I get a segmentation fault, after several minutes, when running pilerimport on a MailDir folder. Here is what strace generates:

It also segfaults when importing another mailbox via imap but this happens after several hours. Will try get a strace for it as well.

I am using 1.3.0.

kind regards

The culprit might be an unclosed and thus leaking file descriptor in src/extract.c. Try the following: edit src/extract.c, and add the following:

There's the following code snippet at the end of the file:

      wait(NULL);
      return;
   }   

Fix it like this:

      close(link[0]);
      wait(NULL);
      return;
   }   

Then run make clean all in the src directory, stop piler, run make install, then start piler, and try the import again.

Thanks for the feedback Janos. The line is already there. I am using 1.3.4 - sorry for the incorrect info above.

OK, no problem. Check if pilertest can process it. Btw, is ./import/maildir/cur/1379449076.M666717P26777.anubis,S=3774,W=3866:2,S the first file pilerimport would process or it has processed many files before reaching this file?

If nothing helps, this might be a parser error. In this case I'd like to see this file myself.

I tried it with pilertest and it seg faults. Did a cat on the file and it looks ok. Will send you the file in a private message. Also this happens after the pilerimport has run for a while so it seems to just be this mail.

Bit bucket doesn't appear to have a private messaging function :(

You may send it as a zip file to my address, see piler -V.
