 Posted: Thu Jan 09, 2003 6:59 pm Post subject: tcpserver & libc.so.6 error - qmail-pop3d flailing |
 |
|
Well, I've got kind of an urgent problem with with my qmail-pop3d server. What tipped me off to it was that qmail-pop3d wouldn't allow me to pop my email. Anyway, after checking /var/log/qmail/qmail-pop3d/current, this is the error message I'm getting:
| Code: | | @400000003e1dc65e328c77c4 /usr/bin/tcpserver: error while loading shared libraries: libc.so.6: failed to map segment from shared object: Cannot allocate memory |
The more urgent aspect of my problem is that, slowly but surely, the log file is filling up with this error message repeated over and over. So I need to figure out how to shut it down. Right now the log file is about 1.1MB and climbing.
Even better would be to figure out what the problem is with libc.so.6. If I were to fix that, you would think my other troubles would go away. I found libc.so.6 in, well you guessed it, /lib. Here's the pertinent listing:
| Code: | -rwxr-xr-x 1 root root 1.4M Dec 12 17:27 libc-2.3.1.so*
lrwxrwxrwx 1 root root 13 Dec 12 17:27 libc.so.6 -> libc-2.3.1.so* |
Doing a qpkg -f libc.so.6 returns nothing, I'm assuming since it's a symlink. But, qpkg -f libc-2.3.1.so says that it's owned by sys-libs/glibc. So I guess that a start to my problem.
Additionally, when I run top or ps-x I see that one of my instances of tcpserver is running as a zombie, [tcpserver <defunct>]. But that's obviously due to the qmail-pop3d problem.
Any ideas of where to preceed with this would be greatly appreciated. Thanks.

Well, for the sake of completeness, I thought I'd post the solution I found. I did a bit of googling and found a link to a message on the gentoo-user mailing list. You can find it archived at http://www.elvisdieguez.us/docs/Gentoo/user-mailingList/msg20495.html. Anyway, here are the contents of that message:
| Quote: | I had the same problem with qmail-pop3d. The program softlimit sets the
ulimit of a program before running it, but these limits were too small.
Have a look into /var/qmail/supervise/qmail-smtpd/run. If you are not so
concerned about security (possible DOS attack), you can change the exec
statement from "exec /usr/bin/softlimit -m 8000000 \n /usr/bin/tcpserver ..."
to "exec /usr/bin/tcpserver ...". Otherwise play a bit with the limits and
have a look into the documentation.

The softlimit in my .../qmail-pop3d/run file was set to 2000000. I changed it to 8000000, to match what was in qmail-smtpd, and now it works. So thanks go to Joerg, wherever you are.
