Re: [Soaplite-devel] Apache 2 - mod_perl - SOAP::Lite 0.69 issue on AIX

[Robert L. <rla...@ao...>]

Generally, what's happened is the module search path has found a older 
version of ABC_DB_SOAP where there was no search method.  It might also 
be that ABC_DB_SOAP doesn't exist.  This could be due to a change in the 
remote httpd.conf.  The reason it might affect one call and not the next 
could be because the SOAP server is actually two or more SOAP servers 
behind a vip or dns rotor.

At least that's what happens to me from time to time.
