[cgiapp] Weird Perl Internal Errors

[David Kaufman]

Hi Jerry,

Though off-topic for this list -- DBI appears to be the culprit -- since 
DBD::* modules usually have XS parts, that's probably where these errors 
are coming from.

You might ask on a DBI mailing list or the appropriate DB Driver list 
(mysql-devel?) and be sure to include your operating system type and 
version, perl version, database type and version and the versions of DBI 
and the DBD driver you're running, and what triggers the error (apache 
restart?  db reads, db writes??  something else?)

Most likely you just have to re-install or upgrade your db drivers (e.g. 
DBD::mysql)

hth,
