Description of problem
======================

1. When ipa-backup is run continuously for few hours, httpd crashes with 7/BUS error and afterwards, IPA services are not restored.

2. While reproducing this issue by running ipa-backup in a loop, ipa-backup eventually fails after file-system becomes full, which is normal. However, the following behaviour is seen:

a) After clearing up the file-system space, IPA services cannot be restarted because httpd continues to fail.

b) Manual start using "systemctl status httpd" also fails.

c) Reboot doesn't restore IPA service, however after reboot, manual restart of httpd works.


Version-Release number of selected component (if applicable)
============================================================

RHEL 7.6+


How reproducible
================

Run "ipa-backup" in a loop, with or without sufficient sleeps in between and wait for file system to become full.

# ipa-backup ; sleep 1; time { RET=0; while [ $RET -eq 0 ]; do ipa-backup ; sleep 1; systemctl status httpd ; RET=$?; echo "**** status=$RET ****"; done; }


Steps to Reproduce
==================

1. Run ipa-backup in a loop until file system becomes full. The sleeps in between don't really matter.

# ipa-backup ; sleep 1; time { RET=0; while [ $RET -eq 0 ]; do ipa-backup ; sleep 1; systemctl status httpd ; RET=$?; echo "**** status=$RET ****"; done; }

2. Once httpd starts failing, it goes into an irrecoverable state i.e. cannot be restored manually even after clearing up disk space.

3. Reboot fails to restore IPA services automatically.


Actual results
==============

Continuously running ipa-backup breaks httpd service.


Expected results
================

ipa-backup should be robust enough to check for available space before disrupting service and shouldn't be able to cause IPA services (especially httpd) to enter an irrecoverable state.
