Thank you Arturo, sure, filled as  https://phabricator.wikimedia.org/T222429. Also filled  https://phabricator.wikimedia.org/T222430, that's an error I didn't forward to the list, but also gets sent fairly often.

@Jaime, sorry for not being clear. I would like to get the error fixed. Also, since I have jsub command in cron (as noted in the email subject), the output cron's mailing must be from jsub itself, not from my code - output from that code should be stored in ~/generate.{out,err}, unless I'm mistaken. If I'm right, the error is in WMF's systems, which should get fixed for sure :). 

Best,
Martin Urbanec

That error doesn't sound familiar to me. Please open a Phabricator ticket with
all the information you have and we will investigate further.
