[documenting for others who might find this thread…]
I looked through all my logs and I found no references to the words malformed or corrupt in any error lines that contained the word error. The only mentions of database were:
ERROR - Waited over 10 seconds for a busy database; giving up.
ERROR - Waited over 10 seconds for a busy database; giving up.
ERROR - Failed to begin transaction (/data/jenkins/server/xxxxxxxxxxx/MediaProviders/MediaSubscriptionDesiredSetManager.cpp:105) (tries=1): Cannot begin
transaction. database is locked
FWIW, I tried the “Optimize Database” option from the troubleshooting menu and PMS then ran for 4 days before crashing again.
Since it’s crashing again and the symptoms look like the signature from New update 1.32.8.7639 crashing randomly on synology nas, I’m just going to revert to the previously-working verion (1.32.7.7621) and await a fix for #14691(as mentioned in that thread) before updating to a newer version.
