Thanks @jan_blaha I had increased timeout to 20000 ms now I am able to generate 1000 plus report pdf, from docx template and data using unoconv.
"templatingEngines": {
"timeout": 60000,
"strategy": "http-server"
}
Will install the latest version of jsreport 2.6.1 and then try to use above configuration.
Thanks for all your help. You guys are doing really a good job, please continue with the good work :-)
Thanks,
Zahid
