<p>Hi Grant,<br /><br />Having too many secondary group members like this could be the problem.<br />I'm not sure if I asked this before, but what action in Webmin was triggering that realloc error? Was it when you clicked on a user to edit him, or when you clicked the link to create a new user?<br /><br /> - Jamie<br /></p><p> On 13/Nov/2007 02:09 Grant Wilson wrote .. </p><blockquote type="cite"> <font size="-1"><font face="Arial">Hi Jamie,<br /> <br /> I wanted to let you know that we fixed this problem. I tried forcing a reinstall of the perl-5.8.8-32.i586.rpm which I got from the Suse mirror but that didnt help.<br /> <br /> All the users on this server, about 1200 of them were added on the command line using a script. There must have been a problem with the script or something similar as I noticed that all of the users had been added to the users, video and dialout groups. They should have only been added to the users group.<br /> I just manually edited the /etc/group file and corrected the video and dialout groups. After that Webmin worked fine.<br /> <br /> The User & Groups module was set to only display 400 users at a time, on the users and groups page it would say that there were too many users to display. Under the groups section it was showing all of the groups but for the above groups, dialout and video, it was showing all of the members so those groups took up about 2 pages displaying all 1200 members. Perhaps that was causing the problem for Webmin?<br /> <br /> </font></font> <pre cols="72" class="moz-signature">Many thanks and kind regards.<br /><br />Grant Wilson<br />CNS,CLS<br />Sales & Technical<br />DcData<br />Tel: + 27 33 3446100<br />Support: 0860-1-LINUX<br />Fax: 0866878971<br /><a href="http://www.dcdata.co.za" class="moz-txt-link-freetext">http://www.dcdata.co.za</a> <a href="reply_mail.cgi?new=1&to=support%40dcdata%2Eco%2Eza" class="moz-txt-link-abbreviated">su...@dc...</a> <a href="reply_mail.cgi?new=1&to=sales%40dcdata%2Eco%2Eza" class="moz-txt-link-abbreviated">sa...@dc...</a> Open Ideas, Open Possibilities - Open Source </pre> <br /> <br /> Jamie Cameron wrote: <blockquote type="cite" cite="mid:119...@we..."> <p>I'd recommend just sticking to the Perl version provided by SuSE, as compiling your own is tricky and may break installed Perl modules. </p> <p>On 11/Nov/2007 22:37 Grant Wilson wrote .. </p> <blockquote type="cite"><font size="-1"><font face="Arial">Hi Jamie,<br /> <br /> I did a Yast update as its running Suse, it did update some of the perl components but I cant tell exactly which ones.<br /> <br /> If I run the following this is what I get.<br /> <br /> proxy:~ # perl --version<br /> This is perl, v5.8.8 built for i586-linux-thread-multi<br /> <br /> Is there an easy what to reinstall perl completely or is that wishful thinking?<br /> <br /> Here are all of the perl related RPMs that are installed.<br /> <br /> perl-Compress-Zlib-1.42-20<br /> perl-HTML-Tagset-3.10-30<br /> perl-TermReadKey-2.30-31<br /> perl-gettext-1.05-31<br /> perl-Digest-HMAC-1.01-525<br /> perl-Date-Calc-5.4-32<br /> perl-DBD-SQLite-1.12-1<br /> yast2-perl-bindings-2.14.0-10<br /> perl-Archive-Zip-1.16-31<br /> perl-Data-ShowTable-3.3-602<br /> perl-Net-Daemon-0.39-8<br /> perl-XML-Parser-2.34-61<br /> perl-Net-Server-0.94-18<br /> perl-libwww-perl-5.805-32<br /> perl-Net-CIDR-0.10-1<br /> perl-Sys-Hostname-Long-1.4-1<br /> perl-Bootloader-0.4.19-2.1<br /> perl-BerkeleyDB-0.31-12<br /> perl-Config-IniFiles-2.39-31<br /> perl-Digest-MD4-1.5-31<br /> perl-IO-Zlib-1.04-32<br /> perl-Unix-Syslog-0.100-59<br /> perl-XML-NamespaceSupport-1.09-31<br /> perl-Bit-Vector-6.4-31<br /> perl-Cyrus-IMAP-2.2.13-24<br /> perl-XML-SAX-0.12-35<br /> perl-XML-LibXML-1.61-15<br /> perl-Net-IP-1.24-1<br /> perl-DBD-mysql-3.0008-12<br /> sax2-libsax-perl-8.1-83<br /> perl-Convert-BinHex-1.119-2<br /> perl-5.8.8-32<br /> perl-Carp-Clan-5.7-14<br /> perl-Convert-TNEF-0.17-292<br /> perl-Digest-SHA1-2.11-20<br /> perl-IO-stringy-2.110-31<br /> perl-Parse-RecDescent-1.80-277<br /> perl-URI-1.35-33<br /> perl-XML-Writer-0.601-17<br /> perl-Crypt-SmbHash-0.12-31<br /> perl-HTML-Parser-3.55-20<br /> perl-X500-DN-0.28-151<br /> perl-Net-DNS-0.59-16<br /> perl-TimeDate-1.16-3<br /> perl-spamassassin-3.1.6-15<br /> perl-Filesys-Df-0.90-1<br /> perl-Archive-Tar-1.30-22.1<br /> limal-perl-1.2.9-5<br /> perl-Convert-UUlib-1.051-31<br /> perl-MailTools-1.74-20<br /> perl-XML-LibXML-Common-0.13-35<br /> perl-Crypt-SSLeay-0.51-147<br /> perl-PlRPC-0.2018-31<br /> limal-ca-mgm-perl-1.2.9-4<br /> MailScanner-perl-MIME-Base64-3.05-5<br /> perl-Sys-Syslog-0.18-1<br /> perl-File-HomeDir-0.65-13.1<br /> perl-Config-Crontab-1.20-10<br /> perl-IO-Multiplex-1.08-14<br /> perl-Tie-IxHash-1.21-618<br /> perl-Cyrus-SIEVE-managesieve-2.2.13-24<br /> perl-DBI-1.52-17<br /> apache2-mod_perl-2.0.2-38<br /> perl-MIME-tools-5.420-1<br /> <br /> <br /> <br /> </font></font> <pre cols="72" class="moz-signature">Many thanks and kind regards.<br /><br />Grant Wilson<br />CNS,CLS<br />Sales & Technical<br />DcData<br />Tel: + 27 33 3446100<br />Support: 0860-1-LINUX<br />Fax: 0866878971<br /><a class="moz-txt-link-freetext" href="http://www.dcdata.co.za" moz-do-not-send="true">http://www.dcdata.co.za</a> <a class="moz-txt-link-abbreviated" href="_unsafe_link_" moz-do-not-send="true">su...@dc...</a> <a class="moz-txt-link-abbreviated" href="_unsafe_link_" moz-do-not-send="true">sa...@dc...</a> Open Ideas, Open Possibilities - Open Source </pre> <br /> <br /> Jamie Cameron wrote: <blockquote cite="mid:119...@we..." type="cite"> <p>So it doesn't look like you are running out of memory then..<br /> This may actually be a perl bug.
