Hello,

In our sandbox environment this morning, I started noticing this error when running tests: UNKNOWN_EXCEPTION, Chatter Feed SOQL Query limit exceeded for this user.

There is nothing in the log output regarding Chatter Feed SOQL query limits, or anything to indicate we are approaching our limitations.  We do not even have Chatter enabled in the sandbox.

  Number of SOQL queries: 0 out of 100
  Number of query rows: 0 out of 500
  Number of SOSL queries: 0 out of 20
  Number of DML statements: 3 out of 100
  Number of DML rows: 4 out of 500
  Number of script statements: 50 out of 200000
  Maximum heap size: 0 out of 1500000
  Number of callouts: 0 out of 10
  Number of Email Invocations: 0 out of 10
  Number of fields describes: 0 out of 10
  Number of record type describes: 0 out of 10
  Number of child relationships describes: 0 out of 10
  Number of picklist describes: 0 out of 10
  Number of future calls: 0 out of 10
  Number of find similar calls: 0 out of 10
  Number of System.runAs() invocations: 0 out of 20

Any ideas on how I can diagnose this?
