[Dxspider-support] User Disconnects when Script Runs - REPOSTED

[Dave Hawes]

DXSpidermen,

I have reposted my 30 Mar message, which asks for assistance in sorting out 
a perplexing user disconnect problem.  Any help would be greatly 
appreciated.

Thanks,

Dave

Many of our users construct spot filters using the "by_state" feature. To keep 
the state data current, a crontab entry runs a script each Wednesday at 
0130Z to fetch the data and load it. The problem is that each Wednesday at 
0130Z all the users are disconnected.

Any suggestions or ideas as to what we can do to eliminate these annoying 
disconnects would be most appreciated.

Thanks and 73 - Dave N3RD

More info:

1. If the script is run manually by the sysop, the disconnects do not occur.

2. The update script has not changed in a long time, but these user 
disconnects started to occur after a fairly recent update of Spider. It took us a 
while to figure out what was going on. We prefer to stay current with Spider.

3. DXSpider V1.55 build 0.102

4. Linux info (Fedora Core 7):

[root at spider-linux ~]# uname -a
Linux spider-linux 2.6.22.5-76.k3wwspider7.fc7 #1 SMP Mon Sep 17 
17:17:26 EDT 2007 i686 i686 i386 GNU/Linux
[root at spider-linux ~]#

5. This is the script that is run by crontab to update the usdb database:

[root at spider-linux /spider/local_cmd]# cat get-usdbraw.sh
#! /bin/sh
#
cd /tmp
rm -f usdbraw*
date >> /spider/local_cmd/wget-usdbraw-log
until wget "http://ftp.w1nr.net/usdbraw.gz"; do date >> 
/spider/local_cmd/wget-usdbraw-log; done
rm -f /spider/data/usdb.v1
cd /spider/perl
perl create_usdb.pl /tmp/usdbraw.gz
cd ../data
chown spideradmin:spider usdb.v1
cd ../perl
./console.pl <<EOF
load/usdb
bye
EOF
