I get this when reloading, but only with the clamav contentscanner
enabled.

Stracing shows:
write(2, bytecode_init: already initialized, 34) = 34
which looks like libclamav complaining that cl_init has been called
twice.

Upstream seem to be pushing the clamdscan contentscanner as a
replacement - contentscanners/clamav.cpp has been removed on trunk and

Note clamdscan isn't enabled in the standard lenny package -

Bug#578778: Failure when using dansguardian -r or dansguardian -g to reload configuration

[Raphael Manfredi]

Package: dansguardian
Version: 2.10.1.1-1
Severity: important

It is not possible to reload dansguardian dynamically (under the dansguardian
UID) by launching dansguardian -r or dansguardian -g.  Both calls end-up
killing dansguardian altogether, with the following errors in syslog:

dansguardian[727]: Content scanner plugin init returned error value: -1
dansguardian[727]: Error loading CS plugins
dansguardian[727]: Error re-parsing the dansguardian.conf file or other 
DansGuardian configuration files

There are no errors during the initial startup, which suggests a bug in the
dansguardian reloading mechanism and should probably be forwarded upstream.

Unfortunately, restarting dansguardian via:

/etc/init.d/dansguardian start

requires root privileges due to the creation of /var/run/dansguardian.pid.

Therefore, the user dansguardian has no way to automatically update the
blacklists without requiring root privileges to restart the process.

And restarting from scratch is disrupting for users as opposed to reloading,
hence the severity of important.
