Dears,
the sitemap script has not been finished yet for several days, without any sitemap file on the output
we are set the Maximum execution time to 0 for unlimited time, but the script stopped working every 30 minutes and showed the screen to continue or start a new session

also, we have set a cronjob to invoke runcrawl.php every 30 minutes but it's the same issue,
on the server, the data directory has a lot of files but not sitemap.xml
Attach PIC2
if we rerun Crawling and set to Continue the interrupted session it's works for about 30 minutes then it interrupted
