Severity: 3-Major


If an operation initiated by the GUI takes more than 5 minutes, httpd times out, causing the GUI to display an error with no indication that the operation is still continuing. Most often, this happens when saving UCS or during a cpcfg operation of a very large configuration. When: -- Activating a new boot location and selecting the 'Install Configuration' operation (System :: Software Management : Boot Locations). -- Generating a UCS archive (System :: Archives). If generating a UCS archive takes over 5 minutes, the Apache httpd process terminates the connection to the backend, presenting this error in the GUI: -- Internal Server Error -- The server encountered an internal error or misconfiguration and was unable to complete your request. -- Please contact the server administrator at support@f5.com to inform them of the time this error occurred, and the actions you performed just before this error. -- More information about this error may be available in the server error log. And logging these errors in /var/log/httpd/httpd_errors: -- hostname httpd[16063]: [proxy_ajp:error] [pid 16063] [client a.b.c.d:53870] AH00992: ajp_read_header: ajp_ilink_receive failed, referer: https://bigip/tmui/Control/jspmap/tmui/system/archive/create.jsp. -- hostname httpd[16063]: [proxy_ajp:error] [pid 16063] (70007)The timeout specified has expired: [client a.b.c.d:5370] AH00878: read response failed from (localhost), referer: https://bigip/tmui/Control/jspmap/tmui/system/archive/create.jsp.


The httpd process times out, rendering the GUI inactive.


GUI operation (e.g. creating a UCS archive) takes more than 5 minutes.


Use tmsh for a save UCS or cpcfg operation on large configurations that might take longer than 5 minutes.
