      We recently started testing in a SuSe environment with MongoDB, and see errors on shutdown in the form:

      2019-05-14T23:07:14.019+0000 E STORAGE [initandlisten] WiredTiger error (16) [1557875234:19015][16136:0x7f9821fd8d40], txn-recover: __wt_cond_destroy, 209: pthread_mutex_destroy: thread group cond: Device or resource busy Raw: [1557875234:19015][16136:0x7f9821fd8d40], txn-recover: __wt_cond_destroy, 209: pthread_mutex_destroy: thread group cond: Device or resource busy

      The relevant call stack is:

      mongod(__wt_err_func+0x90) [0x556d588eccbd]
 mongod(__wt_panic+0x39) [0x556d588ed121]

      There have been bugs in the past in SuSe related to pthread implementations (e.g: https://bugzilla.novell.com/show_bug.cgi?id=865968). We are using a version with fixes for all issues I could find. We should review the eviction thread co-ordination code to make sure it's shutting down threads in a POSIX compliant way.
