as it seems libwrap (=TCP wrappers) is not linked against a lib it should have been. you could disable TCP wrappers support in syslog-ng, or try to preload the library that contains the symbol "rfc931_timeout".

this thread contains more information on the same issue (ignore that it's related to nagios, it seems to be the same issue if you scroll below).

Hope this helps,

This looked like an issue with the library search path. i was able to get around this modifying LD_LIBRARY_PATH

LD_LIBRARY_PATH=/usr/local/lib

# export LD_LIBRARY_PATH

But, now I get the below error,

# /opt/soe/local/syslog-ng-3.3.7/sbin/syslog-ng

Error opening plugin module; module='afsocket', error='Unsatisfied data symbol \'rfc931_timeout\' in load module \'/usr/lib/hpux32/libwrap.so\'.'

Any suggestions on this please...
