Configure core dumps and core dump compression on the Linux host for generating core dumps whenever the NetScaler BLX appliance crashes.

To configure core dumps and core dump compression for a BLX appliance by using the Linux host CLI:

Create a file /etc/security/limits.d/core.conf with the following contents to enable core dumps for all users.
```
*       hard        core        unlimited
*       soft        core        unlimited

```
Add the following line to the file /etc/systemd/system.conf:
```
DefaultLimitCORE=infinity

```
Create a script file /usr/bin/core-compress.sh and add the following lines to the file:
```
#!/bin/bash

gzip -1 > /var/crash/core.$1.$2.$3.gz

```
Add execution permission to the script file by running the following command:
```
chmod +x /usr/bin/core-compress.sh

```

Set the core pattern by running the following command:

echo "|/usr/bin/core-compress.sh %e %p %s" > /proc/sys/kernel/core_pattern
<!--NeedCopy-->

Restart the systemd manager by running the following command:
```
systemctl daemon-reexec

```
Restart the BLX appliance by running the following command:
```
systemctl restart blx

```
