Python Script component which ran with the same code so many times, suddenly returned this exception. It was a one time failure and didn't appear next time the job ran. Also, there was no change regarding the jobs running in parallel. A similar prolem was raised in https://metlcommunity.matillion.com/s/question/0D54G00007ykMzoSAE/ but now solution/explanation was given.
Hi @Faouzi
Possibly has to do with deprecated Python versions so I'd recommend raising a support ticket, if you haven't already. Please update the Community.
Best,
