- While trying to reach the logs via the ADC GUI it says "Could not process the file. File size is too large "
- The file is not that large (less than 1-5 MB) and can be observed via CLI or extracted via SFTP. 
- Only fails via GUI

We can sanitize the files affected with the following command:
 

perl -pi -e 's/[^[:ascii:]]//g' <FILENAME>

Example:
 

perl -pi -e 's/[^[:ascii:]]//g' nsvpn.log

Problem Cause

Non-ascii characters located into the file that is about to be opened. If the log file contains non-ascii characters this message can be expected.

For example via more or zmore the characters shows like this:

 

(0-0) process_kernel_socket: call to authenticate user :Kaml;sh Lc)heyur ^Gut<A7>^n J!un, vsid :1199, userlen 29

 

the <A7> is actually Unicode - translates to  \xa. This breaks the GUI and causes the issue.

 

To test and know if the file has the mentioned characters can be tested with this one liner:
 

 perl -ne 'print "$. $_" if m/[\x00-\x08\x0E-\x1F\x80-\xFF]/' <FILENAME>

It will show the line or lines that contains the offending character.

Could not process the file. File size is too large Non-ascii characters present on the log files.
