Print task causes severe ArcGIS for Server log messages

I've tried to implement a print widget using the print task very closely following this tutorial. However, it is very slow (~60 seconds to export an A3 pdf with default dpi) and I notice the following severe ArcGIS for Server logs:
Has anyone seen this type of vague log?
The python script used:
import arcpy
import os
import uuid
# The template location in the registered folder (as UNC path)
templatePath = '//ourserver/ourtemplatepath
# Input WebMap json
Web_Map_as_JSON = arcpy.GetParameterAsText(0)
# Format for output
Format = arcpy.GetParameterAsText(1)
if Format == '#' or not Format:
Format = "PDF"
# Input Layout template
Layout_Template = arcpy.GetParameterAsText(2)
if Layout_Template == '#' or not Layout_Template:
Layout_Template = "A3 Paysage"
# Extra parameter - georef_info
Georef_info = arcpy.GetParameterAsText(3)
if Georef_info == '#' or not Georef_info:
Georef_info = "False"
# Convert Georef_info string to boolean
if Georef_info.lower() == 'false':
Georef_info_bol = False
elif Georef_info.lower() == 'true':
Georef_info_bol = True
# Get the requested map document
templateMxd = os.path.join(templatePath, Layout_Template + '.mxd')
# Convert the WebMap to a map document
result = arcpy.mapping.ConvertWebMapToMapDocument(Web_Map_as_JSON, templateMxd)
mxd = result.mapDocument
# Reference the data frame that contains the webmap
# Note: ConvertWebMapToMapDocument renames the active dataframe in the template_mxd to "Webmap"
df = arcpy.mapping.ListDataFrames(mxd, 'Webmap')[0]
# ConvertWebMapToMapDocument renames the active dataframe in the template_mxd to "Webmap".
# Lets rename it to something more meaningful.
df.name = Layout_Template
# Use the uuid module to generate a GUID as part of the output name
# This will ensure a unique output name
output = 'WebMap_{}.{}'.format(str(uuid.uuid1()), Format)
Output_File = os.path.join(arcpy.env.scratchFolder, output)
# Export the WebMap
if Format.lower() == 'pdf':
arcpy.mapping.ExportToPDF(mxd, Output_File, georef_info=Georef_info_bol)
elif Format.lower() == 'png':
arcpy.mapping.ExportToPNG(mxd, Output_File)
# Set the output parameter to be the output file of the server job
arcpy.SetParameterAsText(4, Output_File)
# Clean up - delete the map document reference
filePath = mxd.filePath
del mxd, result
os.remove(filePath)
The javascript used to export the maps:
