Knowing how your log file are named and where they are located might provide a better means of getting a list of files to process than manually creating a file containing 2500 pathnames).
Knowing what operating system and shell you're using might help us determine whether or not the operating system you're using has tools to perform these kinds of specialized searches built-in.
Knowing the format of your log files and how you are able to determine whether or not they contain indications that an error occurred will be crucial to determine what kind of processing needs to be performed to achieve your goal.
Samples of log files and the output you hope to produce from those samples would be a huge help if you want suggestions on how to process your log files.
Without basic information like those things listed above, we can make lots of wild guesses that might not be of any help at all.

NAME
approx-gc - garbage-collect the cache of Debian archive files
SYNOPSIS
approx-gc [OPTION]...
DESCRIPTION
approx-gc scans the cache created by approx(8) and finds files that are corrupted or no longer needed. With no options specified, these
files are listed on standard output and removed from the cache.
A corrupted file is one whose size or checksum does not match the value specified in the Packages or Sources file.
An unneeded file is one that is not referenced from any distribution's Packages or Sources file.
approx-gc may take several minutes to finish.
OPTIONS
-c file, --config file
Specify an additional configuration file. May be used multiple times.
-f, --fast
Don't perform checksum validation.
-k, --keep, -s, --simulate
Don't remove files from the cache.
-q, --quiet
Don't print file names.
-v, --verbose
Print the reason for removal of each file.
EXAMPLES
To remove all unneeded or corrupted files from the cache:
approx-gc --quiet
This is run as a weekly cron(8) job.
To list the files that would be removed from the cache, without actually doing so:
approx-gc --keep
FILES
/etc/approx/approx.conf
Configuration file for approx and related programs.
/var/cache/approx
Default cache directory for archive files.
