Just posted this as a response to https://www.cognoise.com/index.php/topic,22623.msg69352.html#msg69352
I am suddenly having the exact same problem in Cognos Analytics 11.2.4FP4.
QuoteCM-SYS-5133 While processing your request, Content Manager waited for 601.023 seconds to access objects that are currently locked.
...repeatedly in cognosserver.log
I found https://www.ibm.com/support/pages/cm-advanced-parameters-help-content-store-locking-issues, but it seems odd that I would need to do any of that since it wasn't needed a few hours ago.
Any idea how I can track down the source of this problem?
