Issue/Introduction

A core dump is generated when listing or registering a connector server by either the IGX UI or by the command line.

For example, the command fails with the following errors: 

/opt/brcm/iga/inst/imps/bin
[igx@server_name bin]$ ./imps_csfconfig list
Error executing operation Command '['/opt/brcm/iga/inst/imps/bin/csfconfig', 'show', 'auth=etaadmin', 'authpwd=/opt/brcm/iga/tmp/imps/ps_listall_auth_file', 'json=yes']' died with <Signals.SIGSEGV: 11>.
[igx@server_name bin]$ 

It creates a core dump file at the following location:

/tmp/hsperfdata_igx
[igx@server_name hsperfdata_igx]$ ls -la           
total 88
drwxr-x---.   2 igx  igx     18 Sep  4 06:02 .
drwxrwxrwt. 126 root root  8192 Sep  4 12:57 ..
-rw-------    1 igx  igx  32768 Sep  4 12:58 4057
[igx@server_name hsperfdata_igx]$ 

We are seeing below errors with imcs server listing. 

For CCS, below errors may be seen in /opt/brcm/iga/logs/imps/

This is **glibc bug #20568** and related issues that were introduced in certain glibc versions and affect wide character stream operations. 

This regression was introduced in glibc versions shipped with RHEL 9.4. The issue affects:

 **glibc versions**: 2.34+ in certain builds

 **Reported in**: Multiple glibc bugs (#20568, #20938, #28258)
