Re: [EP-tech] Issue with bin/generate_apacheconf during EPrints 3.4.6 Installation on RHEL 9.5

Hi Francis,
malloc related issues are very low-level.  This is unlikely to be an issue with the EPrints software itself.  I would check that you have a enough free memory and disk space.  This may be an intermittent issue so a simple reboot may stop you getting this issue if you run generate_apacheconf again after a reboot.
The only significant change to generate_apacheconf in recent versions (specifically 3.4.6, I think) is creating an archive level cfg/static/javascript/auto/99_uploadmethod_file_max_size.js file and setting LimitRequestBody in the Apache config.  By default these will both be set to 1 GiB and restrict the maximum size of file that can be uploaded to your EPrints repository. These are set by the setting $c->{max_upload_filesize} in lib/cfg.d/upload.pl.  There is more information about a potential bug with this in 3.4.6 [1].  However, this potential bug could not cause a malloc error when running generate_apacheconf.
If neither a reboot nor increasing memory (and potentially disk space) fixes you issue let me know.  I cannot really think of anything else I could advise.  It is worth checking to see if any newly created Apache config files/directories have been created in EPRINTS_PATH/cfg/, as that may give a clue to when the error is occurring. 

Regards

David Newman

Dear List Members, I am installing EPrints version 3.4.6 on a RHEL 9.5
system, and I’ve encountered an issue when executing the script
bin/generate_apacheconf. Specifically, I am seeing the following error
message:
malloc(): unaligned fastbin chunk detected 2
Aborted (core dumped)

This error causes the script to abort and prevents me from proceeding
with the installation. I have tried several steps to resolve this,
including ensuring all dependencies are installed and attempting to
reinstall related packages (such as Apache and mod_perl), but the
issue persists.

Here are the details of my environment:

Operating System: RHEL 9.5
EPrints version: 3.4.6
Apache version: 2.4.62
Perl version: 5.32

Please provide guidance or troubleshooting steps to resolve this error.

Thank you in advance for your support.

Best regards, Francis
