We are running MW 1.35 and SMW 3.2.2. Our users just stumbled into a problem when they create category or subcategory pages with a [[category:myname]] tag. This seems to trigger a "change propagation" job. The problem is the job never completes and the page becomes hopelessly locked from further edits. In the MW exception log I see messages like the following:
2021-05-18 20:26:07 ocwikidev mediawiki: [YKQixs046bus0GlZuCCtDgAAAAc] [no req] RuntimeException from line 70 of /home/appl/mediawiki-1.35.1/extensions/SemanticMediaWiki/src/Utils/File.php: /tmp/smw_chgprop_admr20ciahq0_0.tmp is not readable.

The /tmp directory is readable and writable by anyone, so I'm not sure why it is complaining here. Is there some way to redirect that path to someplace other than /tmp? Any other ideas as to how I can resolve this situation for our users?
Thanks in advance,
