  • Applies to:
  • Operations Automation 5.5
  • Business Automation

Symptoms

A big list export to Excel (using the Export To Excel link) fails with the following error:

"Server is temporarily closed for maintenance"

In the Apache error log, /var/log/httpd/error_log, you see these records:

[error] failed to parse response XML packet
[error] [client X.X.X.X] Cannot read response from vzcpcon, referer: URL

Cause

The libxml2 version installed on the Parallels Business Automation - Enterprise (PBA-E) application server is incorrect.

Resolution

Make sure that libxml2 is the correct version:

[root@hostname]# rpm -qa | grep libxml2
libxml2-2.7.6-4.el6_2.4.x86_64

PBA-E 5.4 is shipped with libxml2-2.7.6-4.el6.x86_64 and PBA-E 5.5 is shipped with libxml2-2.7.6-12.el6_4.1.x86_64.rpm. An RPM downgrade is required.

After the RPM downgrade, restart the "www" container:

/etc/init.d/www restart

Also, restart the httpd service:

/etc/init.d/httpd restart
