After my Apache/mod_perl/SOAP::Lite based server is running for a while and working perfectly, I get the following error when making a SOAP call:

Error occurred making remote request call
(Failed to locate method (search) in class (ABC_DB_SOAP) at
/usr/local/perl/lib/site_perl/5.8.8/SOAP/Lite.pm line 2586.)
[download]

where the method is 'search' and the module name is 'ABC_DB_SOAP'

If I try to make the same call right away, it may work or I might get the same error. I assume this is because it uses a different or same httpd child process. As time goes on and the server is used more, the frequency of the errors is higher...

The entry in my httpd.conf file is:

<Location /server>
SetHandler perl-script
PerlHandler Apache::SOAP
PerlSetVar options "compress_threshold => 1048576"
PerlSetVar dispatch_to "/usr/local/mystuff/soap,ABC_DB_SOAP"
</Location>

Reading the perldoc for SOAP::Lite, it mentions:

For dynamic deployment you can specify the name either directly (in th
+at case it will be "require"d without any restriction) or indirectly,
+ with a PATH. In that case, the ONLY path that will be available will
+ be the PATH given to the dispatch_to() method). For information how 
+to handle this situation see "SECURITY" section.

I 'use' various Perl modules in ABC_DB_SOAP.pm and also 'use' them in a mod_perl startup script which is defined in httpd.conf using PerlRequire - for example:

PerlRequire /usr/local/mystuff/conf/startup.pl
[download]

So I think that this is synonymous to the methods offered in the SECURITY section. Here is what the startup.pl file looks like:

#!/usr/local/perl/bin/perl

use ModPerl::Util ();
use Apache2::RequestRec ();
use Apache2::RequestIO ();
use Apache2::RequestUtil ();
use Apache2::ServerRec ();
use Apache2::ServerUtil ();
use Apache2::Connection ();
use Apache2::Log ();
use Apache2::Const -compile => ':common';
use APR::Const -compile => ':common';
use APR::Table ();

use DBI;
use MyModule;
1;

The DBI module is built into my Perl distro, but MyModule resides under /usr/local/mystuff/lib. I use PERL5LIB to include this path to my @INC Could this be an issue?

• OS - AIX 5.3
• Perl 5.8.8
• SOAP::Lite
• Apache 2.2.4
• mod_perl 2.0.3

I should also mention we that the Apache and Perl are NFS mounted - as well as all the Perl modules described above. I know this is probably not the best way to run - but in the environment I am provided, we have little choice.

I have seen this issue mentioned before by Googling for it, Perl Monks, etc... - but have not found any definitive solutions.

Any ideas? Thanks in advance...
